当前,尾矿坝(包括初期坝和堆积坝)的稳定分析方法,除了少量的运用有限单元法以外,其中大量的、普遍采用的是圆弧滑动法(包括改圆弧法和折线法)—即由设计者假定许多条滑动的弧面进行试算,分别计算出每一滑动弧的安全系数,然后,取安全系数中最小者作为坝坡的安全系数,其对应的滑弧为最危 Currently, the stability analysis methods of tailings dams (including initial dams and stacked dams), except for a small number of finite element methods, include a large number of widely used circular sliding methods (including arc method and polyline method) That is, the designer assumes that many of the sliding arcs are tentatively calculated, and the safety coefficient of each sliding arc is calculated respectively. Then, taking the smallest of the safety factors as the safety factor of the slope, the corresponding arc is the most dangerous
