关于大坝的优化设计,主要是指对坝体体形的优化,即运用非线性规划方法,在满足现行设计规范或当今通用设计准则的前提下,求解坝体最优设计断面。本文着重就重力坝、支墩坝,分别阐述如何根据坝体型式的特点和工程设计的要求,选取适宜的数学模型,包括选定设计变量、确定目标函数和建立必要的约束方程,及选择简捷可行的求解方法。
The optimal design of the dam mainly refers to the optimization of the dam body shape, that is, using the nonlinear programming method to solve the optimal design section of the dam under the premise of meeting the current design code or the current universal design criteria. This paper focuses on the gravity dam, pier dam, respectively, according to the dam type and engineering design requirements, select the appropriate mathematical model, including the selection of design variables to determine the objective function and the establishment of the necessary constraint equations, and the choice of simple Feasible solution.
