摘要
崩塌灾害的发生可能会导致人员和财产的较大损失。本文以重庆市万州区徐家坝危岩带为例,通过现场调查分析崩塌产生原因,并以W03、W05号危岩体为研究对象采用定性和定量相结合的方式进行稳定性评价,结果表明:W03号定性分析为基本稳定状态,定量分析中危岩体工况一安全系数为1.5,工况二安全系数为1.47,均处于稳定状态;W05号岩体定性分析结果为欠稳定状态,定量分析中工况一安全系数为1.594,工况二安全系数为1.134,处于不稳定状态。可为本区类似工程提高借鉴或参考。
The occurrence of landslide disasters may lead to significant losses of personnel and property.Taking Xujiaba dangerous rock belt in Wanzhou District as an example,this paper analyzes the cause of collapse through field investigation,and evaluates the stability of W03 and W05 dangerous rock bodies by qualitative and quantitative methods.The qualitative analysis of W03 indicates a basically stable state.In quantitative analysis,the safety factor for condition one of the dangerous rock mass is 1.5,and for condition two,it is 1.47,both indicating a stable state.The qualitative analysis of W05 rock mass results in an under-stable state.In quantitative analysis,the safety factor for condition one is 1.594,and for condition two,it is 1.134.The comprehensive analysis result is a basically stable state,which can serve as a reference for similar projects in this area.
