根据运动稳定理论，将拱坝沿基破坏视为极端运动稳定问题。提出了刚性体法和变形体法两种稳定性分析方法。提出了相应的稳定性判别准则。比较了这些方法的优缺点。运用这些方法对小湾水电站高拱坝的稳定性进行了定量研究，得出了大坝的安全程度。结果表明，除非坝体发生破坏，否则不会发生滑动。
According to the theory for stability of motion, the failure of arch dam along the base is regarded as the problem of stability at extreme state of motion. Two methods, namely rigid\|body method and deformed\|body method, are proposed for analysis of stability. The corresponding criteria for discrimination of stability are suggested. The advantage and disadvantage of these methods are compared. By using these methods the stability of the high arch dam in Xiaowan Hydro project is studied quantitatively and the safety degree of the dam is obtained. It is concluded that the sliding will not occur except for the failure of the dam body is happened.
