The Analysis of Spatial Effect of Deep Foundation Pit in Soft Soil Areas

The spatial effect is very important to the deep foundation pit excavation, but a lot of things were still unknown about it. The spatial effect of a deep foundation pit in soft soil areas was researched through an engineering project monitoring and finite element simulation. The monitoring data shows that the maximum lateral deformation of the retaining wall on the longer sides of the pit was larger than the deformation on shorter sides of the pit. And the appropriate Young's modulus of the soil is recommended for simulation of the deep foundation pit excavation in soft soil areas using Abaqus finite element software.
