| 摘 要： | 通过对古滑坡复活原因的分析和数值模拟,采取以微型抗滑桩为主并结合压力注浆、卸载、反压等工程措施的设计方案,使复合古滑体重新处于稳定状态,确保了道路主线路基及路堑边坡工程的正常施工和长期稳定;结合工程实际对微型抗滑桩进行了力学分析和数值模拟计算,证明其最大轴向力出现在桩体中间位置,而最大剪应力则位于抗滑桩高度的1/3～2/5处.

| Abstract: | Based on the analysis and numerical simulation of ancient landslide revivification,an effective reinforcement measure of micro anti-slide piles combined with pressure grouting,unloading soil and pressing the slope toe was adopted to ensure the road and the cutting slope against slippery.With a practical example,the mechanical analysis and numerical simulation of a micro anti-slide piles are carried out and the result shows that the maximum axial force takes place in the middle and the maximum shear stress is in the 1/3-2/5 height of the pile. |
