摘要
现代城市的迅速发展对生命线工程系统依赖性逐渐增强。地震后生命线工程系统的性能直接决定了灾后生活和生产的恢复以及抢险工作的进行,因此对生命线工程系统进行地震作用下的可靠性分析具有十分重要的意义。本文中主要介绍2种求解大型网络抗震可靠度算法———最小路递推分解算法和最小割递推分解算法。在此基础上,利用这2种算法对沈阳市供气系统进行了分析。研究结果表明,合理选择使用这2种算法可以有效的进行不同地震烈度条件下的大型生命线工程系统的可靠性分析。
With the rapid development of modern cities,their dependences on the lifeline systems increase gradually.The performance of the lifeline systems directly determines the life and production recovery after earthquake as well as the effectiveness of preventing secondary disasters.So it is necessary to evaluate the reliability of the lifeline system under seismic excitations.In this paper,two algorithms,i.e.the minimal path based recursive decomposition algorithm and the minimal cut based recursive decomposition algorithm,which are used to evaluate the seismic reliability of large scale lifeline systems,are introduced firstly.Then the two algorithms are also used in the investigation of the gas supply system in Shenyang.The obtained results show that the two algorithms would be very efficient in evaluating the reliability of large scale lifeline systems under different seismic intensities if they were used reasonably.
