长距离输水管道水头损失计算可视化程序设计与应用

Design and Application of Visual Program for Head Loss Calculation of Long Distance Water Pipeline

长距离输水工程是解决水资源时空分布不均衡,提高资源配置效率的重要手段。利用MATLAB可视化交互式工具GUI,结合管道水头损失计算的相关理论和计算公式,考虑了管道转弯、进出口形式、主管分岔情况和沿线阀门等情况,设计编写了管道水头损失计算的可视化程序,并应用于西南地区某输水工程主干线的计算中。该程序大幅减少了工程设计过程中的人工计算的工作量,有效提高了长距离输水管道水头损失计算的准确性和计算效率。

Long distance water transportation engineering is an important means to solve the uneven distribution of water resources in time and space and improve the efficiency of resource allocation.This paper utilizes MATLAB visualization interactive tool GUI,combined with relevant theories and calculation formulas for pipeline head loss calculation,taking into account pipeline turns,inlet and outlet forms,main pipe bifurcations,and valves along the line.A visualization program for pipeline head loss calculation is designed and written,and applied to the calculation of a certain water transmission project main line in the southwest region.This program significantly reduces the manual calculation workload in the engineering design process,effectively improving the accuracy and efficiency of head loss calculation for long-distance water pipelines.
