高寒高海拔地区某排土场边坡滑坡模式分析与雷达监测效果研究

Analysis of landslide mode and radar monitoring effect on a slope of a waste dump in high cold and high altitude areas

为解决高海拔露天矿排土场边坡安全稳定性监测中存在的常规监测仪器布置以及人员值守的高投入和高风险等问题,本文以西藏某露天铜矿排土场边坡为研究对象,选取典型剖面,通过岩石室内物理力学试验获得坡体岩石物理力学参数,采用简化Bishop和Morgenstern-Price极限平衡法方法分别计算排土场不同滑坡模式下现状边坡各分区稳定性系数,针对高海拔地区的独特气候,利用InSAR监测高海拔排土场边坡形变信息,综合评价高海拔排土场边坡安全稳定性,为高海拔排土场边坡滑坡灾害风险预警与防控提供理论和技术支持。

In order to solve the problems such as the layout of conventional monitoring instruments and the high investment and risk of personnel on duty in the safety and stability monitoring of waste dump slopes of highaltitude open-pit mines,this paper takes the waste dump slopes of an open-pit copper mine in Xizang as the research object,selects typical sections,obtains the physical and mechanical parameters of the slope rocks through indoor physical and mechanical tests of rocks,calculates the stability coefficients of the existing slopes under differ⁃ent landslide modes of the waste dump by using the simplified Bishop and Morgenstern Price limit equilibrium methods,and monitors the deformation information of the high altitude waste dump slopes according to the unique climate of the high altitude areas,comprehensively evaluates the safety and stability of the high altitude waste dump slopes,and provides early warning and prevention and control for the landslide disaster risks of the high altitude waste dump slopes.Provide theoretical and technical support.
