一、拱坝的优化设计用人工方法选定拱坝的坝轴线和设计剖面,要经过反复的修改,比较,工作冗繁,效率很低。采用优化设计方法后,情况为之改观。根据地质和地形条件,确定一个可用的坝址区段之后,可自动优选出最有利的坝轴线和坝体设计剖面。下面介绍作者建立的拱坝优化设计数学模型和优化方法。(一)五心圆双曲拱坝的几何模型坝体水平截面采用三段圆拱,中心拱是水平等厚
First, the optimal design of arch dam Artificial selection of arch dam dam axis and design profile, to be repeated changes, comparison, redundant work, low efficiency. With the optimized design method, the situation changed. Depending on the geological and topographic conditions, the most favorable dam axis and dam design profile can be automatically optimized after an available dam site section has been identified. The following describes the author to establish mathematical model of dam optimal design and optimization methods. (A) Five-heart-circular arch dam geometric model Horizontal section of the dam using three sections of arches, the center arch is the same level of thickness
