采用有限元实体模拟了桥梁桩基在盾构施工后的工况，计算得到了桥梁桩基的横向变形及内部应力情况，从计算结果分析可知，在盾构施工后，墩台桩基表现为竖向承受轴压的状态，且横桥向位移基本可以忽略，盾构的施工对桥梁墩台桩基影响较小，拟采用的桥梁基础设计方案可行。%Bridge pile foundation is simulated by the finite element analysis software after shield tunnel construction. The lateral deformation and the internal stress of bridge pile foundation are calculated. Analysis of the results from the calculation,the pile foundation of bridge is vertical bearing axial load,and the lateral displacement of the pile can be neglected the under the kind of working condition. The influence of shield con-struction on the bridge pier pile foundation is little,and the bridge foundation design scheme is feasible.
