【Abstract】 The multi\|objective optimization model for high arch dam shape under the actions of static and dynamic load is established according to the principle of safety and principle of economy. The fuzzy theory is applied to deduce the evaluation function. The calculation of Xiaowan arch dam is given as an example to demonstrate the effectiveness of the optimization. The volume of the dam is reduced and the stress state as well as the earthquake resistance of the dam are improved.更多还原
