重力式挡土墙断面设计的优化
摘要:为解决挡土墙断面设计指标计算较为繁琐:难以得出最佳结果的问题,以重力式垂直挡土墙断面设计的顶宽和底宽两个主要指标为变量,断面面积最小为目标,按抗滑、抗倾覆性、墙基应力和挡土要求的计算公式,建立非线性优化的数学模型,并应用于贵州省织金县大新桥水利枢纽工程的挡土墙断面设计,采用Excel对建立的数学模型进行求解,得出断面面积最小的各项优化指标。
Abstract:In order to solve the problem that retaining wall cross section design computation is comparatively trouble and it is difficult to obtain the best result, taking top width and bottom width two major indexes in section design of gravity type vertical retaining wall as variable, the minimum cross section area as goal, according to calculating formula of anti-slide, anti-overturning, wall foundation stress and retaining soil request, the mathematical model of non-linear optimization is set up, and applied to the retaining wall section design of Daxin Bridge water control project, Excel is adopted to work out mathematical model, each optimization index of the minimum cross section area is obtained.
