Lifeline systems are these systems that relates to daily life needs, like water-supply, power, telecom, traffic, gas-supply, sewage and heat-supply, and so on. Strong dependence on lifeline system is one of the distinctive characteristics of modern urban area. Lifeline earthquake disaster brings not only property loss, but also functional damage to urban activities and socioeconomic loss. So, since 1971, the earthquake damage forecasting and aseismic design of lifeline systems have been the two of the key problems in the field of Lifeline Earthquake Engineering (LEE). Different structural patterns and performance characteristics existing among these lifeline systems, the database for lifeline earthquake risk assessment is often complicate in order to meet the needs of analyzing model. In general, according to the requirement of lifeline system earthquake risk analysis, the database covers a series of coverages: earthquake hazard data, lifeline structure data, kinds of analysis models, site data, forecasting result data, and aided design measure data. This paper introduces the characteristics of the database related to main six lifeline system, including its function, structural design and design criterion, contents, and update technique. Geological Information System (GIS) is the important developing tool in this database. The data transform technique based on GIS is also presented.
