摘　　要：针对桩位进行研究,以抗滑桩结构为研究对象,运用FLAC3D和ANSYS对5种桩位的抗滑桩结构特性进行模拟研究,得出在保证滑坡安全系数相同时不同桩位下的抗滑桩桩身内力。根据抗滑桩结构设计要求及各桩位的内力图,分析出桩位改变对桩结构的影响。综合5种桩位的分析结果,从工程造价的角度得出合理的加固位置,并用传统的设计方法进行验证,为抗滑桩结构的优化提供参考。The reasonable position of anti-slide piles generally adopt the trial method for reinforcement of the slope, which is always conservative with big safe reservation. Using anti-slide pile location as research object,numerical simula- tion methods such as FLACaD and ANSYS were used to simulate the anti-slide pile structure features of 5 different pile lo- cations. The anti-slide pile the internal forces of each pile location in the case of the same factor of safety. On the basis of the anti-slide pile structure design requirement and the internal force diagram of each pile location, analyze the effect of pile location change to its structure. Comparing with the analysis results of 5 pile locations, the reasonable reinforce location can be obtained from the perspective of the project cost and verified by traditional design methods, providing reference to the global optimization of anti-slide pile structure.
