Abstract: The characteristics of super-deep circular foundation pit project in soft soil area are complexity,dangers, and scarcity. It is of great significance to simulate and predict its deformation accurately. As to the super-deep circular pit with excavation depth of 56.3 m in the deep tunnel project of Suzhou River in Shanghai, a fluid-solid coupled finite element analysis model based on the Biot consolidation theory was established. The deformation and force characteristics of super-deep circular fou... More
