The rupturesurface is to NNE, similar to gradient belt of focal depth, gradient belt of crustal deformation, isoseisms and extended direction of earthquakes.
The stabilization for soil slopes is related to the state of stress. The method of determining the rupturesurface and the mechanism of the slope failure are studied.
将土坡是否稳定与应力状态联系起来，最后探讨了土坡失稳的机理，并提出了确定滑动面空间位置的方法。
