本文是在“考虑地形条件的拱坝优化设计”一文的基础上,利用已有的拱坝优化设计程序,考虑几种不同的坝址标准地形条件下,坝型优化曲线的探讨。目的是为在拱坝方案布置中尽好尽快地利用电子计算机得出经济、合理的优化坝型方案;其次探求在几种坝址标准地形条件下的坝型优化曲线,以便在今后的拱坝优化设计研究中能减少设计变量、取得一些理论依据。本程序是将拱坝优化设计程序中的较优点,采用加权最小二乘法进行统计、并能加权磨光,得出m次(m≤4)拟合曲线方程,监通过适当优选统计获得较优的坝型曲线方程式。
This paper is based on the article “Optimum Design of Arch Dam Considering Topographic Conditions”. The existing arch dam optimization design program is used to consider several different types of arch dam optimization curve under standard terrain conditions. The purpose is to use the computer as soon as possible in the layout of the arch dam to make economic and rational optimization of the dam type scheme. Secondly, to explore the dam type optimization curve under several typical dam site conditions so that in the future arch dam Design optimization can reduce the design variables, to obtain some theoretical basis. This procedure is to compare the advantages and disadvantages of arch dam optimization design program, using weighted least squares method for statistics, and can be weighted polished to obtain m times (m≤4) fitting curve equation, supervised by the appropriate optimization statistics Dam-type curve equation.
