    This document summarizes the key features and capabilities of finite element analysis programs for geotechnical problems. The programs allow users to model the complex behavior of soils and soil-structure interactions, and can analyze problems that cannot be solved using conventional analytical methods. Data can be transferred between programs to ensure reliable design and save time. The programs feature user-friendly interfaces, comprehensive outputs, and built-in databases of soil properties. They can model a wide range of problems through different material models and automatic generation of meshes and boundary conditions. Additional elements like beams, anchors, and surcharges can also be included in the analyses.

    Finite Element Solutions

    Programs for the analysis of geotechnical problems by the finite element


    method (FEM) allow the user to closely model the behavior of real soils and
    structures. They also address problems which cannot be solved by standard
    analytical methods. FEM programs can model the behavior of any soil mass
    and its interaction with structures such as tunnels, collectors, deep foundations,
    sheeting etc. They are also used to calculate settlement and to solve various
    stability problems.
    A key advantage of the GEO5 program suite is the ability to transfer data
    between programs. The structure can be designed or examined using
    traditional analytical or semi-analytical methods. Data can then be transferred
    into the FEM program for an independent assessment of its behavior. Such an
    approach ensures not only a more reliable design, it also saves time.
    The basic program features include:
    • User-friendly application environment
    • Comprehensive graphical outputs
    • Integrated contextual help
    • Metric and imperial units
    • Built-in database of soil characteristics

    Geotechnical Software

    The program is applicable to the modeling of a wide range of geotechnical

    Tunnel
    The Tunnel program is built upon the FEM program platform.

    Geotechnical Software In addition it features:


    • Two options for modeling lining (Beam elements - 1D or standard
    2D elements)
    • Option to create a geometrical model of the lining in a separate
    pre-processor using data in an external format (such as DXF).
    • Simple introduction of the lining into the soil/rock body
    Water (topology correction and mesh generation are fully automatic)
    There are the following options to introduce water into the analysis: • Any number of construction stages
    • The ground water table is input as a continuous interface above or below • Loading of the lining gemetry in DXF format

    • forces in anchors (anchored region)
    Either the total values of individual variables or their changes from stage
    to stage can be displayed.
    Stability analysis
    At each stage of construction the program makes it possible to carry out
    a slope stability analysis of a given structure. In the course of analysis the
    program gradually reduces the basic strength parameters of the soil until
    failure. As a result the program provides a factor of safety corresponding to
    that obtained by classical analyses.

    Plate
    The program performs the analysis of foundation and roof plates of arbi-
    trary shape using the finite element method. It features:
    • Automatic mesh generator for both triangular and quadrilateral elements
    with mesh refinement around points or lines
    • Modeling of subsoil or piled foundation under the plate
    • Concentrated and distributed supports (fixed, spring)
    • Simple introduction of beams using the cross-sectional parameters
    • Loading due to prescribed forces or displacements
    • Any number of loadcases
    • Determination of the required bending and shear reinforcement
