Hello,
I am analyzing the gravity retaining wall soil model in PFC3D. I need to find the stresses acting on the retaining wall due to backfill soil. But when I solve it, the stress along the wall becomes zero after some time.
I am following the following procedure:
-
Create a foundation domain and solve for equilibrium
-
Generate retaining wall and soil and solve the model for equilibrium
-
Provide all the required contact properties to the model
-
Generate measurement spheres at the back of the wall to capture stresses along the wall.
Realistically, there should be stresses along the wall exerted by the backfill soil but I am getting zero. Please help me out with the coding where I am doing wrong. I would really appreciate your help. I can provide the data file if needed.
