Tunneling has certain influences on adjacent pile foundations
even on safety and stability of overall building. The large finite element analytical software ABAQUS is employed to simulate and analyze the influence on the working performance of adjacent pile foundation induced by tunneling based on an engineering example. Firstly the reaction and the change laws of single pile induced by the changes of horizontal distance between adjacent pile foundation and vertical axial line and the change of pile length are analyzed. Then
the responses of pile group induced by adjacent tunneling are studied
and some comparisons between pile group and single pile are made. Finally
some conclusions are drawn to offer the references to related engineering.
