摘要
普贤乡场滑坡位于四川省广元市普贤乡场镇,为了解决该滑坡带来的财产损失及安全威胁,基于该滑坡所在区域地形地貌及滑坡体的基本特征进行大量研究。本文采用极限平衡法对普贤乡场滑坡,分3种工况进行了稳定性研究。计算结果表明:滑坡在天然工况及地震工况下处于稳定状态,在暴雨工况下处于欠稳定状态,并提出采用改沟及弃渣回填工程+抗滑桩+拉裂缝封填相结合的防治措施。
Puxian Township landslide is located in Puxian Township,Guangyuan City,Sichuan Province.In order to solve the property loss and security threat caused by the landslide,a large number of studies have been carried out based on the topography and basic characteristics of the landslide area.In this paper,the limit equilibrium method is used to study the stability of landslide in Puxian township.The calculation results show that the landslide is in a stable state under natural and seismic conditions,and in an under stable state under heavy rain conditions.The prevention and control measures of ditch modification and slag back filling project+anti-slide pile+tensile crack sealing are proposed.
