Abstract: Influence of excavation on pile foundation stability in a certain engineering of Tianjin Economy Developing Zone was analyzed by using ABAQUS program. Failure cases repeatedly take place in soft clay foundation in Tianjin area. The pile foundation in soft soil often is affected by the side excavation of foundation slot, even lead to the pile foundation to tilt and break. This paper establishes a model to simulate these phenomena by finding out the deformation, stress and the deflection of the pile foundation before and after excavation. The results demonstrate that the excavation can seriously influence the deformation, the rotation and the displacement of the pile foundation, the stability of the whole pile foundation; and combining the mechanical feature, the stability and destroy condition of pile foundation are anatomized. It can be a good example for other engineers.

Key words: pile foundation, deformation, excavation, ABAQUS, numerical simulation
