Geotechnical Solution - Capabilities. Analysis Carried Out
ANALYSIS CARRIED OUT WITH THIS MODULE
Seepage analysis
Obtain the water table and water pressure.
Obtain the saturation line for 2D problems.
Export the obtained pore water pressure to slope
stability problems.
The finite element mesh used in the two analyses can be different.
Calculate
filtered flows through boundaries.
Two types of problems that can be solved
with the seepage analysis:
- Confined Flow problem.
- Free Surface problem.
It is possible to consider two different situations for the analysis:
- With drains.
- Without drains.
Seepage boundary conditions available for areas (New).
Slope Stability Analysis
CivilFEM allows to calculate the safety factor against sliding
phenomena in 2D models according to the following methods:
- Classic failure methods.
Fellenius
Bishop.
Janbu and modified Janbu.
Morgenstern price.
US Corps of Engineers.
- FEM results.
- Action on model: seismic effect, loads and hydrostatic load over the slope surface.
The following actions can be considered in the analysis:
- Seismic effects.
- Loads applied directly over the slope.
- Hydrostatic load.
- Results of a seepage analysis can be introduced as input loads to the slope
stability calculation.
Hoek & Brown Failure Criteria
This tool offers ANSYS/CivilFEM users the possibility to work with rock
foundation models, satisfying the Hoek and Brown's failure model, original
(1980) or modified (1992).

Terrain Initial Stress (without strain)
This application calculates inner stresses in the terrain as a result of its self weight. It is very useful, for example, to take into account earth pressure due to excavation processes.
