基于MIDAS/GTS的边坡抗滑桩最优埋设部位的探讨

抗滑桩加固边坡涉及到的一个关键问题是抗滑桩最优埋设部位的确定,借助MIDAS/GTS,采用强度折减法对某边坡安全系数及水平位移随不同桩位的变化进行了对比研究。抗滑桩埋设于坡底时,安全系数及水平位移最小,未能充分发挥抗滑桩的支护作用。抗滑桩埋设于边坡中部时,边坡安全系数及水平位移都达到最大值,最佳埋设部位应位于边坡中间部位。

Optimization of Pile Location for Landslide Mitigations Using MIDAS/GTS

One of the key issues of using pile for the landslide mitigation design is to optimize the location of piles in related tothe slope. The parametric studies on the impact of the pile locations are performed using MIDAS/GTS with the popularstrength reduction method, When the pile is located at the bottom of the slope, the factor of safety and the lateral deformationreach lhe minimum values. The maximum factor of safety and the maximum lateral deformation are obtained when piles are located in the middle of the slope. The optimized location should be in the middle portion of the slope.
