| 摘 要： | 针对三角形断面并非理论上的最优断面的问题,将重力坝上下游做成曲面形式,利用有限元分析软件ANSYS的优化功能,对曲线重力坝的几何参数进行优化。以重力坝上下游曲线方程的系数作为设计变量,以主要荷载下的抗滑稳定和应力控制为约束条件,以单位坝段的断面面积为目标函数,建立混凝土重力坝结构优化设计的数学模型。以30 m坝高为例进行优化分析,得出曲线坝形明显优于传统的实用剖面的结论,为工程设计提供了参考。

| Abstract: | For the issue that the triangular cross section is not the optimal section in theory,the geometry parameters of a curved gravity dam are optimized by using the curved section form in the upstream and downstream and the finite element analysis software ANSYS.Taking the coefficients of the curve equation in the upstream and downstream as the design variables,taking the conditions of stability against sliding and stress under the main load as the constraint conditions and taking the cross section area of the u... |
