太平哨重力坝断面优化设计

Optimal design of the cross-section for the Taipingshao gravity dam

为解决重力坝不同坝段的断面设计指标的计算繁琐问题,以浑江太平哨水电站非溢流坝段上有最大坝高的单位坝段为例,介绍优化设计的原理和方法。以断面几何尺寸为设计变量,单位坝段混凝土方量为目的函数,从解极值问题的数学原理出发,考虑几何、状态、强度、稳定等约束条件,运用EXCEL的规划求解实现模型应用和分析,可供设计参考。

Abstract： In order to solve the complex problem of different cross-section design for the gravity dam, this paper introduces the principle and method of optimal design, with the example of the unit dam section with maximum height in the nonoverflow dam of Taipingshao hydropower plant in Hunjiang River. Based on the extremum problem of mathematical theory, taking the cross-section geometrical dimension as variable, the minimum cross-section volume as goal,model applying the solver tool in Excel can carry out, considering the restrict condition of geometry ,state, intensity and stabilization. This paper also analyzes the modle ,which is useful for designers.
