摘　　要：在总结生命线系统地震中相互作用特点的基础上,探讨了生命线系统的地震性态破坏特点,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生命线系统相互作用下的地震破坏机理,建立了一套考虑相互作用的生命线系统地震性态评价新方法.In recent decade, seismic performance assessment of lifeline systems is highly regarded in order to reduce earthquake risk of lifeline systems. However, earthquake loss of lifeline system is still huge although there are obvious progresses in the field of lifeline earthquake engineering. The pivotal problem is that the interaction mechanisms existing different lifeline systems is not still revealed. According to earthquake damage survey, interactions of lifeline systems are the important factor to induce huge earthquake loss. A new method based on Geographical Information System and Fault tree analysis is presented to study the interaction of lifeline system in this paper. Several parameters are firstly defined based on the survey and statistical analysis of earthquake damage of lifeline systems. Then, the qualitative and quantitative models of interaction are constructed by the use of these parameters; the lifeline system is equivalent to network system, which consists of simply node, complicated node and arc. Finally, an illustration is given to testify the new method, and the results show that forecasting result from this method has a good precision compared with real earthquake damage.
