摘　　要：通过对某悬臂式抗滑桩发生倾斜过程分析,从桩身结构强度、桩嵌入长度、桩后工程加载、桩前土体水平承载力、桩前开挖扰动等方面剖析了抗滑桩倾斜原因;桩后超载、桩前临空导致桩倾斜,采用预应力锚索加固的处置方案,为类似工程处置提供参考。By analyzing the tilting process of a cantilever anti-slide pile,the reasons for the tilting of anti-slide pile are analyzed from the aspects of pile structural strength,pile embedding length,post-pile engineering loading,horizontal bearing capacity of soil in front of pile and excavation disturbance in front of pile.Pile tilt is caused by overload after pile and air in front of pile The solution of prestressed anchor cable reinforcement is adopted to provide reference for similar engineering disposal.
