CFVR3303 - Retaining Wall 2D Geometry checking

Retaining wall depth + anchorages length checking

This example test the geometry of the model generated with the Retaining Wall tool in Geotechnial Module, comparing the size of the model with the variables introduced.
The example loads the test model which creates the following structural materials:

C40/50 concrete for the wall.
S400 steel for the reinforcement and anchorages.
Fe 430 steel for the anchorages shapes.

The terrain is defined with four layers:

Layer 1: Sand Well Graded. 2 m thickness.
Layer 2: Gravel Well Graded. 8 m thickness.
Layer 3: Diorite. 5 m thickness.
Layer 4: Sand. 6 m thickness.

The wall is 0.9 m thick.
The construction process is defined as follows:

Step 1: Terrain is excavated to level 1000m.
Step 2: Terrain is excavated to level 999m.
Step 3: Terrain is excavated to level 998m. An anchorage is placed at level 998,5m.
Step 4: Terrain is excavated to level 997m.
Step 5: Terrain is excavated to level 996m.
Step 6: Terrain is excavated to level 995m.
Step 7: Terrain is excavated to level 994m.
Step 8: Terrain is excavated to level 993m.
Step 9: Terrain is excavated to level 992m.
Step 10: Terrain is excavated to level 991m. An anchorage is placed at level 991,5m.
Step 11: Terrain is excavated to level 990m.

Element types used in the model: PLANE182, BEAM3, LINK8, TARGE169, CONTA171

Needed CivilFEM Modules:
Geotechnical Module
Bridges and Civil Non Linearities Module
Advanced Prestressed Concrete Module

The example cannot be launched on an educational license.
