改进的“两相优化法”用于排水管网优化设计

Modified "Two-phase Optimization" for Optimized Design of 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、流速三方面对管段进行优化设计。用两相优化法和改进的方法分别对一实例进行优化设计,分析其结果。改进的方法较原方法优化效果更好,工程造价更低。

The modified 'two-phase optimization' is applied in the optimized design of the pipe diameter and burial depth of the drainage network, which optimizes the pipeline design sequentially from fullness, slope and flow rate. Comparison is made between the 'two-phase optimization' and the modified one to optimize a project design respectively and results show that the modified method is better, with lower engineering cost.
