改进的“两相优化法”在排水管网优化设计中的应用

The Application of Ameliorative Method of Double Phase Optimization in Optimal Design for Drainage Networks

介绍了改进的“两相优化法”在排水管网管径和埋深的优化设计中的应用。改进的方法依次从充满度、坡度、流速3方面对管段进行优化设计。通过算例分析可知,改进的方法较原方法优化效果更好,工程造价更低。

The application of ameliorative method of double phase optimization in optimal design for the diameter and embedding depth of conduit in drainage networks is presented.This method conducts optimal design in three aspects, permeated degree, gradient and velocity of flow in turn. The effect of the ameliorative method is better than the former method through analysis on cases and the cost of project is also lower than the former one.
