N2 - Water-supply system is one of the important lifeline systems; its performance has a great effect on the post-earthquake rescuing, reconstructing and rehabilitating of daily production and living. The paper presents one methods to calculate the systemic reliability of the water-supply system considering the interactions between water-electric systems under earthquake invading. To assess the interaction between water supply and electric system, the graph theory (GT), network analysis (NA) is applied. Based on the GT and NA, both of water supply and electric systems are consisted of nodes and links, and the nodes are farther divided into two types: simply and complicated. The simply nodes mean that their seismic performance will not be affected by the performance of electric system, but the complicated nodes will be done. The interactions between water supply and electric systems are considered in complicated nodes through the definition of several parameters based on the statistic analysis. The links are applied to describe the pipeline element and electric transmitting elements, and their performance levels are estimated considering the effect of the fault movement, ground displacement, and peak ground acceleration. Based on the reliability of nodes and links, the water-supply systemic reliability is calculated by use of GT and NA. Lastly, compared with seismic performance of water supply in one actual earthquake in China, one illustration is given to test the reliability of the proposed method in this paper.
