For the influence and countermeasure of a deep foundation excavation on vicinal slope retaining structures, there is a finite element simulation for the process of excavation before strengthening existing pit slope with MIDAS GTS, and a detailed analysis for the destructive characteristics of existing excavation slope. During excavation, it was obtained that the failure modes of existing excavation slope get close to the slope of cantilever support on the whole, and some strengthening measures can be taken for existing pit slope for this feature, such as adding to micropiles for strengthening ...
