Updated with the correct diagram. The soil displacement with longer surcharge is lower, why ? shouldn't the longer the surcharge , the more critical it is ? Hence, the higher the soil displacement is ?
Thanks for your reply. I am still new to Plaxis. Yes, they are the same model with same loading but different geometry, it appears that the displacement of soil is higher when the applied surcharge is shorter . The results posted earlier weren't FOS phase, they are the results for final...
I also found that when the region of surcharge applied is short, the slip circle shown is like toe circle, when the region of surcharge applied is long, the slip circle is like base failure. How does the slip circle failure mode relate to the movement of soil ?
When I model an open up excavation in the computer model , I found that when the surcharge applied on slope is long enough , the soil movement (downwards under the surcharge region) is lower , when I model the short region of surcharge, I found that the soil movement underneath the region of...
