摘要
以覆盖层地基上混凝土面板堆石坝工程造价最小为目标,以趾板长度、上游坝坡角、主堆石料与下游堆石分界坡角、上游坝坡角为设计变量,以坝体几何尺寸为约束,建立了面板堆石坝的数学优化模型。介绍了MATLAB优化工具箱的使用,并选择合适的算法求解优化模型。结果表明:MATLAB优化工具箱可方便快捷的求出优化结果,同时提高设计效率。
Taking the lowest cost of the concrete face rockfill dam as object function, the length of the toe slab, upstream dam slope angle, the slope angle of boundary of lord of rockfill and downstream and the slope angle of upstream dam as design variables, the dam geometry size as constraint, the paper established the mathematical optimization model for the concrete face rockfill dam. This paper introduced the use of MATLAB optimal toolbox and choosing appropriate algorithm for solving optimization model. The results shown that the optimization results can be obtained quickly by MATLAB optimal toolbox and improved the design efficiency.
