摘要
根据合流制管网系统的图论和矩阵算法 ,提出节点递归优化算法 ,以节点为研究对象 ,优化合流制管网系统。本算法能解决管网在交汇点处上下游管段衔接计算问题、溢流井设置问题 ,克服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。
According to the drawings and matrix algorithm of the combined piping network system the paper puts forward node recurrence optimum algorithm. It takes the nodal as the study object to optimize the combined piping network system. The algorithm can solve the calculation problem connection of pipe section on the upper and down reaches of the piping network at convergence place and to overcome the difficulty undetermined control points to reach the optimum target of the minimum cost, and it can directly take the nodal elevation as the restrained condition to fully consider to use the original piping or solve the intersect problem of the underground piping. And it is verifies by examples.
