突变理论研究重力坝的抗滑稳定安全性
Research on the Stability against Sliding of a Gravity Dam Using Calastrophe Theory
受施工条件的限制，重力坝的抗剪强度往往较低，坝体所受的水平推力也较大，因此在设计中，都要验算沿坝基面的抗滑稳定性。而大坝及基岩的结构失稳本身就是一种典型的突变现象。本文建立了尖点突变模型对大坝的稳定性进行描述，最后以向家坝重力坝为例，进行建模分析，其结果与有限元强度折减法的结果一致。
Because of the construction condition, Anti-shears strengthen of most gravity dams is low, and horizontal forces is large. As these factors, the stability against sliding of a gravity dam should be considered in the dam design. Instability of a dam and its bases is typical catastrophic phenomenon. In this paper, the stability of a dam is researched through establishing a catastrophic model. Finally, the xiangjiaba gravity dam was introduced in as an example, and the result is in accordance with that of the finite element strength reduction method.
