摘要

摘要: 降雨是边坡失稳破坏的主要诱因之一,边坡的滑动和破坏与雨水入渗密切相关。本文选取铜绿山古铜矿遗址Ⅶ号矿体西侧的露天采场东侧边坡为分析对象,根据工程水文地质条件和边坡产状建立数值计算模型,利用GEO-STUDIO软件的SEEP/W模块,模拟不同降雨强度下的边坡内部渗流特征,并结合SLOPE/W模块计算出各种降雨工况条件下边坡稳定性系数。模拟结果表明,随着降雨强度的增加,露天采场东侧坡体内部的渗流场发生显著变化,且边坡稳定性系数与降雨强度呈负相关的变化规律。

Abstract: Rainfall is one of the major causes for instability and failure of slopes,as a result,slope sliding and destruction are closely related to rainfall infiltration.This paper selected the eastern slope of the open pit on the west side of the Ⅶ orebody of the Tonglüshan Ancient Copper Mine site as the analysis object.Firstly,numerical calculation models were set up according to the engineering hydrogeological conditions and the occurrence of the investigated slope.Then,by using the SEEP/W module of the GEO-STUDIO software,the internal seepage characteristics of the slope under different rainfall intensities were simulated.Finally,combining with the SLOPE/W module,the coefficients of slope stability under various rainfall conditions were calculated.The results have shown that with the increase of rainfall intensity,the internal seepage field of the eastern slope of the open pit mine changed significantly,and the coefficient of slope stability was negatively correlated with the rainfall intensity.
