摘要
本文分析了露天矿顶、底帮岩层与边坡的相互关系,提出了具有普遍意义的由顺层滑动面和切层滑动面形成的最危险组合滑动面的试算确定法。指出对于组合滑动面来说,与坡面成45°-φ/2夹角的切层滑动面不一定是最危险的滑动面。
A trial method is proposed in this paper for calculating the most dangerous composite slip surface, which combines slab mode with circular mode, based on relation between slope and top wall or the foot wall. It is pointed out that the circular plane, at an angle of 45°-φ/2 to slope surface, is not always the most dangerous slip surface.
