本文以暗管排水系统的总费用最小作为目标函数,将排水暗管的管径、埋深、间距、比降作为变量,使这些变量满足确定排水管间距的渗流方程,满足吸水管和集水管的管径、埋深和比降的限制约束以及管内的防冲、防淤约束,用综合约束函数双下降法求解非线性规划。方法简单易行,可在一般微型机上进行。
In this paper, the minimum total cost of underground pipe drainage system is taken as the objective function, and the diameter, depth, spacing and ratio of drainage pipe are taken as variables to make these variables meet the seepage equation to determine the distance between pipelines, Diameter, depth and drop restrictions and the tube within the anti-red, anti-siltation constraints, with comprehensive constraint function double descent method for solving nonlinear programming. The method is simple and easy, can be carried out in the general microcomputer.
