中文摘要: 根据刚果(金)排土场边坡实际情况,以软弱夹层厚度与降雨量为变量,进行了两者耦合与边坡安全系数的影响研究,基于Geostudio-SEEP/W、SLOPE/W模块的计算能力,应用Bishiop方法计算了在不同夹层厚度、不同降雨量下的边坡最小安全系数 ,同时进行了排土场边坡的滑动面分析及渗流分析。研究表明:降雨量增加,水位逐渐上升,抗剪强度减弱,安全系数逐渐降低;软弱层厚度增加,滑面半径增大,抗滑力减小,安全系数减小,降低速率大于降雨。
Abstract:Congo (gold) mine slope based on the actual situation, with weak intercalated layer thickness and rainfall as variates, the coupling and the slope safety factor research, based on Geostudio - SEEP/W and SLOPE/W module of computing power, Bishiop method is applied to calculate the minimum safety factor of slope under different rainfall and different interlayer thickness, meantime analyzed the sliding surface and the seepage of dump slope.Research shows that increased rainfall result in rewater level rising gradually, shearing strength reduced, safety factors decreasing gradually;The thickness of the intercalated layer increased, the radius of the sliding surface increased, the anti-sliding force decreased, the safety factors decreased, which the reduction rate is greater than the rainfall.
