本文所研究的是排水管网计算机程序设计的新方法一两相优化法,并用该方法研制了计算机程序。该程序能在满足设计规范和其它约束条件的基础上,确定最优流速,最优充满度和最优管径等,从而大幅度地减小了管道系统的埋深和工程造价。当地面坡度较大时,又能通过计算减小管径,降低工程造价,或者恰当地确定跌水井的位置和高度。最后将水力、高程和工程造价等计算结果,以表格的形式打印出来。
This article studies the new method of computer programming of drainage network, a two-phase optimization method, and uses this method to develop a computer program. The program can determine optimal flow rate, optimal fullness and optimal pipe diameter on the basis of meeting the design specifications and other constraints, thereby greatly reducing the depth of the pipeline system and the project cost. When the slope of the ground is relatively large, the diameter of the pipe can be reduced by calculation to reduce the construction cost, or the position and height of the drop well can be properly determined. Finally, the calculation results of hydraulic power, elevation and project cost are printed out in the form of a table.
