摘要

运用数值模型试验方法，对预应力锚索抗滑桩治理后滑坡的加固效果进行分析和探讨。试验表明，FLAC3D数值模拟模型试验方法直观，且可以量化地评估加固前后滑坡和预应力锚索抗滑桩的变形特征，受力情况和计算滑坡体稳定性系数。加固后滑体的水平和垂直位移显著减小，滑体压力转移至桩体，稳定性系数大幅度提高。该方法适用于预应力锚索抗滑桩应用于滑坡的加固效果评价和加固机制分析

Abstract

Reinforcement effects of prestressed anchorage piles applied to landslide are analyzed and discussed by numerical simulation model test method. The results show that: The force and load-deformation characteristics of landslide treated by prestressed anchorage pile can be investigated intuitively and quantitatively

and the safety factor can be calculated with this method. The vertical and plane deformations of landslide are decreased obviously

the landslide force is diverted to anti-landslide pile

and the safety factor was improved observably. This method is available to evaluate the reinforcement effect and interaction mechanism of pre-stressed anchorage piles applied to landslide
