摘要

基于三维抗滑桩加固边坡稳定性极限分析法，采用拟静力法分别对水平地震作用和竖向地震作用下的三维抗滑桩加固边坡稳定性进行了分析，得到以下结论：在水平地震力作用下，边坡的三维效应(限制宽度 B/H)对抗滑桩的最有效位置几乎没有影响，但在较大水平地震强度下，最有效的桩位置更靠近边坡顶部；竖向地震力方向向下时(kv>0)，竖向地震强度绝对值|kv|越大，边坡临界滑动面会变浅，坡顶的破坏区域变小，最有效的桩位置随宽高比 B/H 的减小而越来越远离坡顶，但当竖向地震力方向向上时(kv<0)，竖向地震强度绝对值|kv|越大，边坡临界滑动面会变深，坡顶的破坏区域变大，最有效的桩位置随宽高比 B/H 的减小而越来越接近坡顶，并且三维边坡的安全系数要远大于二维解。

Abstract

Three dimensional seismic stability of slopes reinforced with a row of piles is analyzed using the kinematic theorem of limit analysis within the framework of the pseudo-static approach. A 3D rotational failure mechanism is adopted to yield the upper bound to obtain the factor of safety. Parametric studies are carried out to explore the effects of seismic intensity，the end effects of slope failure and the effects of pile location on the safety of the reinforced slopes. The results demonstrate that the most effective location of the piles is close to the slope crest under large horizontal seismic intensity. The three-dimensional effects on the most effective location of the piles are significantly different when the vertical seismic force is up or down.
