摘要
本文基于静、动力荷载作用下高拱坝的安全性与经济性 ,建立了高拱坝体型多目标优化设计模型 ,利用模糊理论提出了多目标优化的评价函数 .以小湾拱坝为例 ,进行了体型优化设计 ,优化体型与初始体型相比 ,在坝体体积、应力指标和抗震能力上都得到了改善 .
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.
