| 摘 要： | 在岩石边坡中，当出现平面滑坡时，如果边坡内没有确定的滑面，滑面的临界倾角不仅仅是边坡倾角和破坏面摩擦角的函数，而且还应该是滑体高度、破坏面的黏聚力和岩体重度的函数．通过推导和计算得知，滑面的临界倾角与边坡倾角呈线性关系，与破坏面摩擦角呈二次函数关系，与滑体高度呈对数关系，与破坏面的黏聚力呈负指数关系，与岩体重度呈二次函数关系．此外，当边坡中有张裂缝和水时，滑面的临界倾角还与张裂缝的深度和水位高度有关.

| Abstract: | If the planar failure arises without fixed plane in rock slope, the critical inclination of failure face is not only the function of slope angle and friction angle of failure face, but also the function of the height of failure part, the cohesion of failure face, and unit weight of failure body. According to deduction and calculation the critical inclination of failure face has a linear relation with the slope angle, a quadratic function relation with the friction angle of failure face, a logarithmic relation with the height of failure part, a negative exponent relation with the cohesion of failure face, and a quadratic function relation with the unit weight of failure body. In addition, when there are tension crack and water in the slope, the critical inclination has relations with the position of crack and the level of water. |
