【摘要】 提出节点递归算法优化雨水管网系统.根据雨水管网的图论和矩阵算法,用管网联系矩阵描述整个管网,采用节点递归优化算法,以节点为研究对象,克服了管网在交叉节点处上下衔接计算和控制点不易确定的困难,达到了费用最低的优化目标;并可直接以节点标高为约束条件,充分考虑利用原有管道或解决地下管线交叉问题.并通过实例进行了验证.更多还原

【Abstract】 This paper presents an optimal recurrence method for storm water system with node-objected strategy based on graph theory and matrix theory.With the link matrix,storm water networks is established,and the method can overcome the difficulty of calculating the elevations in joints linking upstream and downstream pipes and defining the node,which controls the burying depth of storm water system.By running the program,the optimal design of the whole storm water network system can be obtained.Based on node-objected strategy,with coordinate transformation method and enumerative method,the proposed algorithm can optimize the storm water pipe system minimize the objective investment function,and can solve the underground pipes,crossing problem by defined joints elevations.更多还原
