山区输配水管网沿线流量与节点流量的简化计算研究

目前全国范围内不断有农村饮水工程投入建设。其中,供水工程的管网布置与输水管管径的确定是输配水工程设计计算的两大课题。在管网与输水管的布置完成后,其管径确定得合理与否就成为影响输配水系统的投资与运行费用的主要因素。本文介绍沿线流量与节点流量计算方法,并结合典型山区农村供水工程输配水设计实例进行验证分析。

Study of Flow Capacity and Node Flow Capacity Simplified Calculation Along Mountainous Water Distribution Pipe Network

More and more rural drinking water projects are constructed across the country at present, wherein water supply project pipeline network layout and water transfer pipe diameter determination are two major topics for water distribution project design and calculation. After the pipeline network and water distribution pipelines are arranged, whether pipe diameter is determined rationally is an important factor to affect investment and operation cost of water distribution system. Flow capacity along the line and node flow capacity calculation methods are introduced in the paper. Typical mountainous rural water supply project water distribution design example is combined for verification analysis.
