基于某尾矿库目前标高和最终标高的概化模型,在正常水位和洪水位两种工况下,采用Geo-Studio软件中的SEEP/W模块进行渗流场模拟,并应用SLOPE/W模块对每种条件下尾矿坝的稳定性进行数值计算,得到最危险滑动面和最小抗滑稳定系数。结果表明,在排渗设施正常工作的情况下,尾矿坝边坡稳定性均满足规范要求的最小安全系数,但终高洪水位时坝体安全系数的富余不是很大。同时验证了尾矿坝安全系数随着库内水位的上升以及浸润线深度的变化规律。
基于某尾礦庫目前標高和最終標高的概化模型,在正常水位和洪水位兩種工況下,採用Geo-Studio軟件中的SEEP/W模塊進行滲流場模擬,併應用SLOPE/W模塊對每種條件下尾礦壩的穩定性進行數值計算,得到最危險滑動麵和最小抗滑穩定繫數。結果錶明,在排滲設施正常工作的情況下,尾礦壩邊坡穩定性均滿足規範要求的最小安全繫數,但終高洪水位時壩體安全繫數的富餘不是很大。同時驗證瞭尾礦壩安全繫數隨著庫內水位的上升以及浸潤線深度的變化規律。

Based on the model of present elevation and ultimate elevation ,in the conditions of common water level and flood level ,SEEP/W ,the seepage analysis module of GEO-Studio is utilized to simulate the changing regularity of seepage field and then the results will be substituted into the module of SLOPE/W to conduct the simulating calculation for the stability of the tailings dam ,finding out the minimum safety factor and sliding surface .The result shows that ,in the conditions of drainage facilities working normally ,the slope stability of tailing dam can satisfy the requirements of the minimum safety co-efficient ,but in the ultimate elevation flood water level and the safety coefficient is not high enough .At the same time ,the effect of rising water level on the seepage line position and the dam stability is analyzed .
