露天金属矿排土场边坡稳定性评价及时序性分析

Time series analysis and stability evaluation of opencast metal mine

大阳沟排土场可能发生滑坡的形式为排土场的内部滑坡。采用极限平衡法对最危险截面在现状和降雨条件下进行稳定性分析,表明在降雨条件下会降低排土场的稳定性。运用时序模型做出分析和预测,通过和现场监测对比较为吻合。同时加强动态的降雨监测。

The landslide may occur inside of dump in the Daganygo.The stability analysis of the most dangerous sections was carried out by using the limit equilibrium method.And with the present and rainfall stability of the analysis,it will reduce the stability of the dump.The model is analyzed and predicted by time series model,Compared with field monitoring,which is in good agreement with practice.Especially strengthen the monitoring of the rainfall.
