摘要
在总结生命线系统地震中相互作用特点的基础上,提出定量评价生命线系统相互作用的三个指标。利用网络分析方法,将生命线系统等效为节点和弧段单元体系,并将节点进一步划分为复杂和简单两种类型,建立考虑相互作用影响下的复杂节点故障树,在此基础上并进一步利用故障树分析方法和地理信息系统的网络分析方法探讨了地震作用下生命线系统网络破坏机理,最终提出了一套考虑相互作用的生命线系统,震害预测新方法。
Presents the earthquake damage characteristics of lifeline systems with interactions for earthquakes of recent 30 years. Three parameters are defined to describe the form and degree of interactions within lifeline systems. Destruction models considering interactions in main lifeline systems are constructed from a system point of view. Based on the geographic information system and fault tree technique, a new network analysis method of earthquake damage forecasting is presented for lifeline systems with interactions.
