Analysis of Global Safety Degree of Arch Dam Based on Catastrophe Theory

Abstract:

Article Preview

The cusp catastrophe theory was introduced to the evaluation of the global safety of a system of an arch dam and its foundation, and the relevant quantitative instability criterion was established. Based on the overload nonlinear FE analysis of a planned arch dam, the global safety degree of this arch dam was 2.75 according to the instability criterion of the cusp catastrophe model of plastic strain energy, and the evaluation result was in agreement with the transfixion criterion of the plastic yield area.
