Hello everyone, I’m performing an excavation of a rock slope, I build the model, assigned material characteristics, assigned joins properties then I applied the in-situ stresses, assigned the boundary conditions to the supports, applied the gravity, when I run for the first time the stresses are ok, some displacements are developed (but I reset them in the next step), but the problem is when I perform the first excavation the displacements goes all the way up and the values are relatevely low. I need to know if there is anything wrong o something I missed to assign.
I’'l put some pictures for reference:
System with different materials and discontinuity properties:
Displacements after first run (reset to 0)
Displacements after 1st excavation
Thanks for your attention
