基于参数分类迭代的拱坝体形优化方法及应用
Optimization of arch dam shape based on parameter-classified iteration and its application
摘要
Abstract
In order to simplify the optimization algorithm and improve the efficiency of the arch dam,and to further improve the comprehensive performance of the arch dam,this paper firstly studied the different influences of various shape parameters of an arch dam on its stress condition and volume,classified those into two categories,namely,thickness and curvature radius.Then proposed the parameter-classified iteration based on the different sensitivities of the stress condition and volume to these two parameters.Finally achieved a rapid reduction in the volume of the dam while ensuring that the dam stresses meet the design specifications.Based on the arch dam shape obtained from this optimization algorithm,further adjustments could be made in accordance with actual engineering needs,resulting in a final shape that improved multiple functional objectives.This approach combining algorithm and engineering experience for optimizing the arch dam shape was successfully applied to the Yebatan Arch Dam on the Jinsha River.It achieved excellent results,including a reduction of 93,000 m3 in the basic shape volume at the construction stage compared to the tender design stage,and simultaneous improvements in various indicators such as dam stress,deformation,and adaptability.关键词
