GEO5 is a software suite from Fine for geological surveying and geotechnical planning.

History

The version GEO 1.0 was created in 1989, with GEO 2 the first graphical outputs were created, then in 1995 GEO 3 received a completely graphical user interface. In 2000 a first version for Microsoft Windows followed, in 2005 GEO 5 was launched and supported international standards for the first time, from 2009 also Eurocodes and localization. The following year, the company entered the Russian and US markets, then in 2011 also France.

Solutions

Stability calculation

Stability calculation of earth slopes

The stability of a generically specified slope consisting of soils or weathered rocks can be solved using the Slope Break program. Slope Break can determine the worst-case circular or polygonal slip surface, solve specific groundwater scenarios, and include stabilization elements such as anchors, nails, reinforcements, and/or piles. The Stabilization Pile program can be used to check deformation and bearing capacity of piles.

Stability of rock support

The program Rock Stabilization solves the stability of rock slopes according to planar or polygonal sliding surfaces. It is also possible to analyze rock wedges using the stereographic Lambert projection.

Stability of artificial slopes

Slopes reinforced with geotextiles can be designed using the Reinforced Earth program. In addition to global stability, this program can perform the required verifications such as internal stability, slippage on the reinforcement, tilting and slippage or bearing capacity of the foundation soil.

The Nail Wall program is designed for the analysis of slopes secured with nails and shotcrete or steel mesh. In addition to the overall stability, the internal stability of the nails and the design of the reinforced concrete or steel mesh cover can be checked.

EM calculation

Groundwater can be calculated using the numerical seepage flow calculation in the slope failure - water flow extension module. It considers both steady and unsteady water flow.

The stability of generic slopes can also be solved numerically in the FEM program. The program uses a stepwise reduction of M-C shear strength parameters (ϕ, c), which can be performed during each construction phase. If required, the numerical seepage analysis can be solved with the FEM extension module water flow.

Excavation design

Verification of shoring structures

The detailed verification of a shoring construction is performed in the program Shoring Wall, in which the construction is loaded by earth pressures depending on its deformation. The program checks the load-bearing capacity of the shoring structure, the internal stability of the anchor system, the load-bearing capacity of the individual anchors, hydraulic verifications such as heave and piping and/or the vertical load-bearing capacity.

Design of the shoring structure

The initial design of the shoring structure can be performed using the program Shoring Wall Preliminary Design. The main results of this program are the required minimum depth of the structure in the ground, the preliminary internal forces and the anchor forces.

This program is used to analyze the stability of rock support and rock wall for a specific type of failure, including a plane or polygonal shear plane or rock wedge, and to verify slope stability. Rock support The structure can be loaded by active pressure, increased active pressure or resting pressure.

FEM calculations

Numerical analysis of complex excavations, often combined with other structures, can be performed with the FEM program. It is possible to model all types of cross-sections, anchors, beams, etc. An advantage is the possibility to use different nonlinear material models for certain soil types, e.g. cam clay or hypoplastic clay.

Retaining wall

Conventional retaining walls Heavy concrete or stone retaining walls can be solved using the Heavy Retaining Wall program. In this program, the user can define the cross-sectional shape of the wall. Cantilevered walls made of reinforced concrete can be calculated with the Angular Retaining Wall program. Bridge abutments with the option of wing walls can be solved in the program Abutments

Segmental retaining walls

Segmental walls consist of several blocks. This includes gabion walls, which can be sized using the Gabion program. The Block Retaining Wall program is used to design walls from prefabricated blocks. A special program Redi-Rock stone retaining wall works with blocks of the Redi-Rock Inc system. In each of these programs the anchoring of the blocks to the geogrids is included.

The Reinforced Masonry program is intended for walls made of reinforced masonry with a concrete foundation.

Walls from reinforced soil

Special cases of retaining walls made of reinforced soil can be solved with two programs. The Reinforced Earth program considers soil reinforced with geo-reinforcement, while the Nail Wall program uses nails and shotcrete and/or a steel mesh.

The general structure is loaded with earth pressure and analyzed in the Earth Pressure program.

Shallow foundations

Spread and strip foundations

The most common type of shallow foundation is the spread footing. The different foundation types can be designed using the Single Foundation or Single Foundation CPT programs.

The Single Foundation program uses the M-C strength parameters (ϕ, c) to determine the bearing capacity of the foundation soil, while the Single Foundation CPT program determines the bearing capacity directly on the basis of the field tests performed. In addition to static penetration tests (CPT), it also works with standard penetration or pressure measurement tests (SPT, PMT).

Both programs are able to calculate settlements, design reinforcement of RC foundations and work with foundation strips that are continuously loaded, e.g. under walls.

Slabs and foundation mats

The Slab program designs foundation slabs (mats) and slabs. It determines deformations, internal forces and reinforcement of a generally specified slab using the finite element method (FEM). The slab can have different support types, e.g. piles or elastic subgrade. The program can also analyze floor slabs.

Foundation strips

For non-uniformly loaded foundations, e.g. under columns, we recommend the use of the program Beam with which the internal forces in a beam on elastic foundation can be determined.

Pile foundations

Design of a single pile

The Pile program is used to calculate the vertical and horizontal bearing capacity of a single pile. This calculation can be performed using various analytical methods and numerically using the spring method. The program uses the load-settlement curve from which the settlements of the pile can be determined. The program also designs the longitudinal and shear reinforcement for the RC piles. It is also possible to check the bearing capacity of timber and steel piles.

The vertical bearing capacity and settlements of the pile can also be determined directly from the results of field tests (CPT, SPT) in the program Pile CPT.

Pile group analysis

Pile groups or micropiles connected by a rigid plate can be calculated using the Pile Group program. The analysis can be performed analytically for cohesive and noncohesive soils or numerically using the spring method. When using the spring method, the bearing capacities of individual piles or micropiles can be verified in the Pile or Micropile programs. The data is automatically transferred to both programs.

Pile groups can be solved directly based on field test data in the Pile CPT program.

Micropile analysis

The micropile program designs micropiles loaded by normal forces and moments. It can check the vertical bearing capacity of the shaft and root. The program also performs buckling checks and is able to consider the effects of corrosion.

Settlement analysis

Foundation settlements

Settlements of foundation structures are solved within specialized software for shallow and deep foundations:

Settlements of shallow foundations Settlements of deep foundations

Terrain settlements

The calculation of subsurface settlements, e.g. under an embankment or a surcharge, can be solved analytically in the program Settlement. A 1D consolidation calculation can also be performed in this program.

For more complex tasks, the settlements can be calculated numerically in the FEM program, where any loads including cyclic loads can be modeled. With the extension module FEM Consolidation, consolidation calculations with vertical and horizontal water discharges can also be solved numerically.

Settlements behind the shoring structure

After the deformation of the shoring construction into the excavation, the soil behind the shoring construction settles. This calculation is performed in the shoring wall program.

Settlements above the tunnel

The calculation of the so-called settlement trough can be performed in the Settlement Trough program, including the effect of the settlements on buildings located in the overburden area. The settlement depression can also be determined numerically in the FEM program, the main program for tunnel calculation.

Tunnels and shaft structures

Design of tunnels and collectors

The basic program for the calculation of bored, excavated or backfilled tunnels is the FEM program, which can be used to solve any geotechnical problem using the finite element method. The program includes many linear and nonlinear material models, an advanced mesh generator, and options for easy modeling of beam and contact elements. The tunnel lining can consist of beam and/or area elements.

Sequential excavation methods

The FEM Tunnel extension module provides special options for modeling tunnels using the sequential excavation methods (SEM, NATM), such as the gradual increase of the strength of the primary lining due to the aging of the shotcrete or the gradual decrease of the interaction of the surrounding mass (Lambda method).

Design of manhole structures

The calculation of loads on circular shaft structures can be performed with the program Shaft. The program determines the spatial earth pressure and determines the internal forces on each floor.

Geological modeling

Creation of a 3D subsurface model

The basic program for creating a 3D model of the subsurface is the Stratigraphy program.

The modeling procedure corresponds to the work of a geologist:

Input of data from the subsurface investigation - boreholes, wells, CPTs, SPTs, etc. Interpretation of the entered data and creation of soil profiles Creation of 2D cross sections similar to CAD programs Automatic creation of a 3D model according to the entered cross sections All entered data can be used to create geological logs geological logs.

The GEO5 Stratigraphy program is designed for processing data from geological surveys (boreholes, DPT, CPT, SPT, DMT, ...), for creating 2D and 3D subsurface models. Stratigraphy

Data export to GEO5 programs

The 3D model can also be used as input data set for all other GEO5 programs - soil profiles of any coordinates can be copied into 1D programs, e.g. for shallow or deep foundations, and the whole section can be transferred into 2D programs, e.g. for stability calculations. All entered data can be published in the logs.

The entire model can be exported to other programs in various formats, e.g. IFC, DWG, DXF, LandXML, and then used for BIM modeling.

Modeling of earthworks

Modeling of Earthworks Stratigraphy - Earthworks various modifications can be made to the final 3D model, such as excavating excavations, creating slopes, or modeling linear and planar structures. At any stage of construction, it is possible to calculate the volumes of backfilled and excavated soil, or analyze the change in the volume of water above the ground.

Geological survey

Data collection

GEO5 Data Collectoris a mobile application for data collection in the field or in the laboratory that works with both cell phones and tablets. The app uses templates for stratigraphy and allows you to enter data in the field, use maps and GPS, and add photos, videos, or audio recordings. The mobile app and the stratigraphy program can then share this data. The app is available on Google Play and App Store.

The Point Cloud program allows processing point clouds (up to 100 million points) and exporting them to the GEO5 Stratigraphy program or to external LAS files.

It includes simple editing tools for removing buildings and vegetation, modifying water surfaces, and reducing the number of points.

Geological sources

The Stratigraphy program can be used to retrieve cartographic information and borehole measurements from public sources. Results of specific geologic investigations are entered into the program. All field tests can be recorded, i.e., boreholes, wells, CPTs, SPTs, pressure gauges, dilatometers, etc. Data can be entered directly or imported into the program in many formats.

Geological cross sections

The Stratigraphy - Cross Sections extension module provides special options for printing and exporting geological sections. The creation of sections is similar to the work in CAD programs, but is usually much easier due to the direct generation from the 3D model.
