| 摘 要： | 2006年7月吾尔塔米斯沟发生了一起浅层推移式滑坡,坡体处于基本稳定状态,但存在着一定的安全隐患。通过现场勘察总结了滑坡结构特征,并通过实验测试确定了滑坡的物理力学指标,建立起与滑坡主勘探线剖面对应的滑坡稳定性分析模型,运用传递系数法计算该滑坡不同工况的稳定系数,对滑坡体稳定性进行评价。上述研究结果表明,该滑坡稳定系数为1.147,处于较稳定状态,但在发生强烈地震、短时强降雨或有较大规模坡顶、坡脚扰动时,稳定系数均小于1,处于欠稳定状态,进一步发生较大规模滑动的可能性很大。

| Abstract: | In July 2006,a shallow sliding landslide occurred in Wuertamisigou.Since then,the slope has remained basically stable,but there are certain safety risks.In this study,we learned about the structural characteristics of the landslide through on-site investigation,summarized the structural characteristics of the landslide,and determined the physical and mechanical indicators of the landslide through experimental tests,and further established the landslide stability analysis model corresponding to the main exploration line profile of the landslide,using the transfer coefficient method Calculate the stability coefficient of the landslide under different conditions,and then evaluate the stability of the landslide body.The above research results show that the current stability coefficient of the landslide is 1.147,which is in a relatively stable state.However,when there is a strong earthquake,short-term heavy rainfall,or large-scale slope top and foot disturbance,the stability coefficient is less than 1,which is under In a stable state,the possibility of further large-scale sliding is very high. |
