Geotechnical Engineering Software GEO5

Geotechnical Engineering Software GEO5 GEO5 software suite is designed to solve various geotechnical problems. The easy -to -use suite consists of individual programs with an unified and user-friendly interface. Each program is used to analyze a different geotechnical task but all modules communicate with each other to form an integrated suite.

1.Stability Analysis Slope Stability

Rock Stability

MSE Wall

Slope Stability Analysis

Slope Stability is the basic program for modelling layered slopes, embankments or earth cuts. The program solves slope stability problems assuming either circular or polygonal slips including an automatic search for the most critical surface. There are several adopted approaches starting with simplified methods (Fellenius, Bishop) up to rigorous methods (Spencer, Morgerstein, Janbu, Sarma) that fulfill all boundary conditions. The program communicates with all programs used for analysis of retaining structures and walls.

Analysis of Rock Slope Stability

The program analyses the stability of rock slopes and walls for a specified type of failure, including a planar or polygonal slip surface or soil (rock) wedge.

Mechanically Stabilized Earth Walls design

The MSE Wall program analyzes slopes reinforced with geo-reinforcements. It contains a built-in database of geo-reinforcements supplied by leading producers. However, it is still possible to adopt an arbitrary geo-reinforcement defined by the user.

2. Excavation Design

Sheeting Design

Sheeting Check

Shaft

Sheeting Design - Design and Analysis of Sheet Piles and Other Retaining Wall Types The program is used for design and analysis of variety of retaining structures such as anchored retaining wall and sheet pile retaining wall. It provides required pile embedment lengths (for fixed and hinged toes), bending moments, internal forces and forces in anchors. Final analysis of multiplied anchored walls should be provided by GEO5 Sheeting Check program (elastoplastic nonlinear method). Sheeting design provides only preliminary analysis.

Sheeting Check - Excavation Design and Analysis (Non-linear Elastic/Plastic Model)

The program is used for the analysis of shallow and deep excavations and retaining structures (anchored, non-anchored cantilever and prop or strut walls) by the method of elastoplastic nonlinear analysis . Program allows the accurate modelling of structural behavior during construction process, determination of the displacement field, the internal forces in the structure and the post-tensioning of anchors.

Shaft - Circular Shaft Design Program Shaft serves for analysis of spatial earth pressures on circular shaft and determination of internal forces on the structure.

Earth Pressure - Calculation of Earth Pressures The program computes basic earth pressures (active, passive pressure, and pressure at rest) acting upon an arbitrary shaped structure.

Abutment - Bridge Abutment Analysis The program serves to verify abutment and wing wall design. It allows for checking the abutment for overturning, translation, bearing capacity of foundation soil and for dimensioning of decisive concrete or reinforced concrete sections (including wings), respectively.

Redi Rock Wall - Retaining Wall Analysis The program Redi Rock wall is used to design and check a retaining walls made from blocks produced by Redi-Rock, Inc (USA). Program was developed for Redi-Rock, Inc. and is available free of charge. The program is developed as a part of GEO5 software and includes freeware versions of program Slope Stability and Spread Footing.

Piles - Analysis of a Single Pile (Both Vertical and Lateral Load) The program is designed to analyze vertical bearing capacity of a pile loaded both in tension and compression, pile settlement as well as bearing capacity of a solitary pile. Verification analysis can be performed employing EN 1997-1 standard or classical approach (limit states, factor of safety)

Pile Group - Analysis of Group of Piles (Raft Foundations, Pile Cap) The program performs the analysis of group of piles (raft foundation with a rigid foundation plate) using both spring method (FEM) and analytical approaches. The program assumes a rectangular grid of vertical piles, general loading acting on an upper plate. Geological environment consists of horizontal layers. Both floating piles and piles fixed into the subsoil can be considered.

Pile CPT - Pile Design Based on Cone Penetration Test Results (CPTs) The program verifies the bearing capacity and settlement of either an isolated pile or a group of piles based on the results provided by (static) cone penetration tests (CPT)

Micropile - Design and Analysis of Micropiles The program verifies tubular micropiles (micropiles reinforced by a steel tube). When calculating the micropile bearing capacity, the program checks both the micropile root and shaft.

Plate - Foundation Mat, Slab-on-Grade Foundation Analysis by the Finite Element Method The program performs the analysis of foundation mats, slabs on grade of any shape using the Finite Element Method.
