摘要
渗漏管网的流分析是进行供水管网震后功能评价,从而实现在系统层次进行抗震设计的基础。在正常使用阶段,渗漏也是供水管网设计必须考虑的问题。本文介绍了供水管网渗漏分析的两类基本模型。在此基础上,给出了考虑渗漏模型的供水管网流分析的实施步骤。为了比较无渗漏模型和渗漏模型的差异及不同渗漏模型对计算结果的影响,对一典型供水管网进行了无渗漏管网模型的流分析和不同渗漏模型的带渗漏管网的流分析。分析结果表明,合理的渗漏模型是正确评价供水管网服务能力的基础。
The leakage analysis of the water supplying networks is necessary to evaluate the post-earthquake function of the system, and then attain the anti-seismic design on the systematic level. At the same time, leakage is an unavoidable factor in the design for a supplying network at ordinary state. In the present paper, two sorts of leakage models are introduced. Then, the processes of flow analysis method based on several occasions (with or without leakage) are depicted. A case study shows different results according to different leakage models.
