| 摘 要： | 大坝及岩基的结构失稳、破坏等本身就是一种典型的突变现象。以裂缝开度时效分量的变化作为依据建立了大坝失稳的尖点突变模型，对大坝的稳定性进行了描述，并对大坝失稳的机理做了简要的分析，最后以某水电站为例，进行了建模分析，其结果与实际情况吻合较好。

| Abstract: | The failure and breakage of dam and its rock foundation is a typical catastrophe phenomenon essentially.Based on the aging component mutation of the degree of crack in dam,a cusp catastrophe model was established through using catastrophe theory to describe the stability of the dam,and the mechanism of failure of dam briefly.An example of typical crack of a dam in a hydropower plant was analyzed using the mutation model developed.The result accords with the reality. |
