The lifeline interaction is the mutual effect between a lifeline system and other lifeline systems in the same district under seismic conditions. In other words, the reliability of a lifeline system, in addition to system oneself earthquake resistant performance, still depends on the reliability of other lifeline system which have functional connections or physical proximity with the lifeline system. In this paper, the mechanism of lifeline system interaction is analyzed and the method and its corresponding result for categorizing the lifeline system in terms of interaction are presented. various methods for the different kind of interaction are reviewed in this paper. For the function interaction of the lifeline system, an all-round study method is recommended. A WebGIS based aided decision-making method for the post-earthquake restoration of multi-lifeline system is also presented. Meanwhile, some key-points for lifeline system interaction are discussed.
