| 摘 要： | 岩石边坡的稳定性主要受结构面控制, 由结构面切割形成的楔形体失稳是岩石边坡的主要破坏形式之一.通常采用赤平极射投影对楔形体的稳定性进行分析,只能获得定性的结论.楔形体作为刚体,其稳定性可按照刚体极限平衡法结合赤平极射投影图计算.同时利用数学推导,可对楔形体进行三维计算.而采取实体比例投影,可将问题转化为二维问题,且其计算成果在一定误差范围内.

| Abstract: | The stability of rock slope is mainly controlled by discontinuities,so the instability of wedges due to discontinuities cutting is one of the main rock slope failures.Usually wedge stability is analyzed by the stereographic projection method,only qualitative conclusion can be obtained.As a rigid body,wedge stability can be calculated by the rigid body limit equilibrium method in combination with stereographic projection drawings.Meanwhile,3D calculation of the wedge body can be made by use of mathematical d... |
