Because of the different slope angles of super deep FP (foundation pit) on the slope, different soil properties and lithology of excavation materials, seepage pressure of groundwater along the slope, pore water pressure in super deep FP and other factors, people don't know the deformation mode and failure mechanism of this kind of deep soft soil slope super deep FP. In this paper, Midas GTS software is used to simulate the deformation mechanism of a deep soft soil slope super deep FP in Qujing, Yunnan Province. The results show that the numerical simulation of the excavation process of this deep soft soil slope super deep FP is feasible and reasonable, which provides first-hand design information for similar projects in this area, and plays a good reference and guiding role in the construction of similar deep soft soil slopes in this area. It is particularly important and meaningful.
