摘　　要：分析了地下水对顺层岩坡优势面水力学作用的机理，指出了水头高度与稳定性系数之间的关系，提出了导致边坡失稳的极限水头值ｈ１．用于岩坡预测预报的预警水头值ｈａ以及水力学稳定性判据ｈｃ，并给出了计算方法。The hydraulic effect of the ground water on the preferred planes in consequent rock slide is ana- lyzed in this paper. The relationship between water head and stability coefficient is discovered The val- ue of limit water head. h1 , which leads to the stability failure of rock slide, the value of alarm water head, ha, which is used for prediction, and, hc, the hydraulic criterion of stability are put forward . More- over,their algorithm are given.
