• Design Considerations
  • Overall stability
  • Reinforcements (structural / fiber)
  • Lateral movement
  • Long term stability (earthquake / rainfall)
  • Water pressure
  • Construction sequence (inclination)
  • Solution
  • GTS NX has an effective options for dealing with structural or fiber reinforcements. For the detailed analysis, the structural elements including some pretention can be introduced in a construction stage analysis so that the forces and moments in the structure can be computed along with the interaction between the structure and ground.

    Moreover, a slope stability analysis can be carried out with selected structural elements and load component applied to the ground. In order to simulate field conditions, structural and ground components can be activated and removed at different stages of construction.

    The friction based interface element enable for simulating soil-structure interaction behavior. All kinds of possible field situations such as rainfall, earthquake, wall loading, deformations, or stability, GTS NX has a method of verification for given conditions.

  • Construction stage analysis can be used to simulate the construction process of the ground using numerical analysis. Construction stage analysis consists of multiple stages and loading/ boundary conditions, as well as elements, can be added or removed at each stage. This loading/ boundary or element change is applied at the start of each stage. GTS NX can use following types of analysis features to conduct Construction stage analysis.

    Stress-Slope Analysis
    Analysis of stress and slope stability during the construction process

    Seepage Analysis
    Stage by stage Steady state seepage analysis, Stage by stage Transient seepage analysis
