摘要
对于苏海图露天矿北帮高陡边坡,分析了降雨-爆破震动耦合作用对边坡稳定性的影响机理,利用S-SAR边坡雷达监测技术,实时监测分析降雨-爆破震动作用下边坡变形数据.结果表明在强降雨季,边坡稳定性较差.当降雨-爆破震动同时作用时,边坡表面变形呈现波动上升趋势,较雨季期间,单一降雨作用对边坡稳定性影响较大,是滑坡灾害的重点发生时间段.研究结果可为降雨-爆破耦合作用下的高陡边坡稳定性研究及进一步推动边坡雷达监测技术在露天矿山工程中的应用提供一定参考.
Abstract
For the high and steep slope of the north gang of Suhaitu open pit mine,the mechanism of rainfall-blasting vibration coupling on slope stability was analyzed,and the slope deformation data under rainfall-blasting vibration were monitored and analyzed in real time by using S-SAR slope radar monitoring technology.The results show that in the strong rainfall season,the slope stability is poor.When rainfall-blasting vibration at the same time,the surface deformation of the slope shows a fluctuating upward trend,compared with the non-rainy season period,rainfall-blasting coupling has a greater impact on the stability of the slope,which is the focus of the landslide disaster time period.The results of the study can provide a certain reference for the study of the stability of high and steep slopes under rainfall-blasting coupling and further promote the application of slope radar monitor-ing technology in open-pit mine engineering.
