摘　　要：利用有限元软件,基于强度折减法,分析了全埋式抗滑桩不同的自由段长度和嵌固端长度对滑坡稳定性的影响,结果表明,滑坡的安全系数随着全埋式抗滑桩自由段长度和嵌固端长度增加而增加,当大于一定长度后安全系数变化不大,全埋式抗滑桩的自由段长度不宜小于滑坡体厚度的1/4,嵌固端长度不宜小于滑坡体厚度的1/2。Using the finite element software,based on the strength reduction method,this paper analysed the influence of different free length and fixed end length of buried anti-slide piles to the stability of landslide.The results showed that the safety coefficient of landslide increased along with the free length and fixed end length of buried anti-slide piles,when more than a certain length,the safety coefficient changed little.The free length of buried anti-slide piles should not less than 1/4 of the thickness of landslide body,the fixed end length should not be less than 1/2 of the thickness of landslide body.
