摘　　要：随着城市地上空间和地下空间的大规模开发,地铁盾构隧道穿越建筑物基础的复杂情况越来越多地出现,当隧道距离桩基础小于安全距离时需要考虑隧道施工对建筑物的影响。总结评述了当前主要的几种对障碍桩的处理措施。With the large-scale development of the city space and the underground space,the complicated situation that subway tunnel passing through the buildings foundation is emerging more and more.It needs to be considered the influence of tunnel constructions to buildings when the distance between the tunnel with the pile foundation is less than safe distance.This paper summarized and reviewed several current major processing measures to the obstacle pile.
