日本自来水管网管理及风险控制

Management and Risk Control of Water Supply Network in Japan

基于城市的快速发展过程导致供水方面的需求不断增加等问题,介绍了日本自来水管网的发展历程,从日本管网现采用的抗震设计、管压和流速的设计、供水管网布局模式等方面介绍了日本水力风险的控制策略,从自来水水质、管道事故控制对策、水质控制指标、末端水质控制策略等方面介绍了日本水质风险的控制策略,并介绍了日本最新的自来水管网管理相关研究。最后,依据日本的发展经验提出对我国管网建设与管理的建议。

In the process of rapid development of cities,the demand for urban water supply is increasing.This paper introduces the development process of water supply network and the control strategy of water risk in Japan from the aspects of Japanese seismic design,pipeline pressure and flow design,and layout of water supply network.The paper also introduces the control strategy of water quality risk in Japan from the aspects of tap water quality,pipeline accident control,water quality control indicators and terminal water quality control strategy,and reports the latest research on water supply network management in Japan.According to the experience from Japan,this paper puts forward suggestions for the construction and management of water supply network in China.
