用故障树分析法对城市排水管网系统进行可靠性分析

北京作为国际化大都市,其排水管网系统运行安全至关重要。简要介绍了故障树分析法的由来、分析方法及功能,并用这种方法分析北京市排水管网系统的可靠性,对管网可能发生故障的危险进行分析、评估、预测,找出系统的薄弱环节,以期将系统可能发生的损失降低到最小程度并为建立新排水管道的风险指标体系提供科学依据。

Fault Tree analysis for reliability of urban drainage pipe network

As a modern city just like Beijing,it is important to assure the safety of the drainage network.This paper briefly introduced the origin,analysis method,and functions of the Fault Tree analysis method and built a appropriate Fault Tree to analyze the reliability of drainage pipe network of Beijing.It also analyzed,evaluated,predicted the possible danger of the drainage pipe network to find the weakness of the network,so hoped to decrease the possible system damage to the minimum and offer scientific referen...
