This paper presents an intelligent simulation system for an earthquake disaster assessment system based on a development platform of a Geographic Information System (GIS) and Artificial Intelligence (AI). This system is designed to identify the weakness of the structure and inflastructure system in pre earthquake conditions, quickly assess earthquake damage and make an intelligent emergency response for the public and government during the earthquake and post earthquake. The system includes the following functions: intelligent seismic hazard assessment, earthquake damage and loss evaluation, optimizing emergency response and post earthquake recovering plan. The principle, design criteria, structure, functions and test results of this system are described in this paper. Based on its functional characteristics, this system is composed of four parts: an information database, analytical modules, an intelligent decision making sub system and a friendly user interface. There are 132 coverages and 78 analytical modules included in the information database and analytical modules. With this system, seismic disaster mitigation strategies can be verified during a pre earthquake, and be executed at the time of an earthquake and post earthquake; the earthquake resisting capacities for an entire city and all of its communities can be greatly enhanced. To check its reliability and its efficiency, this ystem has been tested based on a scenario earthquake event in one city, and the related results have also been given in this paper. At the present, this system has been installed and used in Daqing City, China. After running for almost l0 years, this system has successfully been used in rehearsing of seismic disaster mitigation and post earthquake emergency response. Simultaneously, an optimizing aseismic retrofitting plan in Daqing City has been executed based on results fl'om this system.

Not only in daily living, but also in seismic rescuing, water-supply system is one of the most important lifeline systems; its performance plays an key role on the post-earthquake rescuing, reconstructing and rehabilitating of daily production and living. The paper presents one methods to calculate the earthquake damage of the water-supply system considering the interactions between water-electric systems during earthquake. 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.

Lifelines, such as pipeline, transportation, communication, electric transmission and medical rescue systems, are complicated networks that always distribute spatially over large geological and geographic units. The quantification of their reliability under an earthquake occurrence should be highly regarded, because the performance of these systems during a destructive earthquake is vital in order to estimate direct and indirect eco-nomic losses from lifeline failures, and is also related to laying out a rescue plan. The research in this paper aims to develop a new earthquake reliability calculation methodology for lifeline systems. The methodology of the network reliability for lifeline systems is based on fault tree analysis (FTA) and geological information system (GIS). The interactions existing in a lifeline system are considered herein. The lifeline systems are idealized as equivalent networks, consisting of nodes and links, and are described by network analysis in GIS. Firstly, the node is divided into two types : simple node and complicated node, where the reliability of the complicated node is calculated by FYA and interaction is regarded as one factor to affect performance of the nodes. The reliability of simple node and link is evaluated by code. Then, the reliability of the entire network is assessed based on GIS and FTA. Lastly, an illustration is given to show the methodology.
