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。
One of the key issues involved in anti-slide piles reinforcement slope is the determination of the optimum embedded anti-slide piles. With MIDAS / GTS, the strength reduction method is used to compare the safety factor and horizontal displacement of a certain slope with the change of different piles the study. Anti-slide pile buried in the bottom, the safety factor and horizontal displacement of the smallest, failed to give full play to the role of anti-slide pile support. When the anti-slide pile is embedded in the middle part of the slope, the safety factor and horizontal displacement of the slope all reach the maximum value, and the best buried part should be located in the middle part of the slope.
