| 摘要： | This report describes an evaluation process for simulating the seismic performance of large geographically distributed water supply systems and characterizing their performance in terms of reliability and serviceability. The evaluation process makes use of probabilistic seismic hazard analysis tools, theoretical and empirical relationships of pipeline responses, hydraulic analysis of heavily damaged water networks, and multi-scale simulations of complex water systems. The process provides information for decision makers to assess the economic and social impacts of lifeline disruptions due to earthquakes, and works in combination with a computer code, Graphical Iterative Response Analysis for Flow Following Earthquakes (GIRAFFE) developed by the authors to simulate heavily damaged piepline networks and presents the simulation results in GIS format. The framework for decision-making presented in this report describes five basic activities: seismic hazard characterization, system definition, system component response evaluation, global system response evaluation, and consequences assessment. The methodology was applied to evaluate the seismic performance of the water supply operated by the Los Angeles Department of Water and Power (LADWP). |
