Assessment Seismic Damage Of Reservoir Based On GIS Application

This thesis is part of the a Social Welfare Projects of Ministry of Science andTechnology of China Titledd:”Reservoirs in the Yellow River disaster chainprediction of strong earthquakes”(serial number8-44).Through simulating damageassessment mode, the seismic damage of concrete dams in the upper reaches of theYellow River are analyzed using relevant hydraulic model. Forecast on flooddamages of the important towns in the Yellow River is made under certain scenarioand.the water levels rise with times and flood arrival at certain places in submergingregions are mapped or calculated to assess the disaster damage. This operationsystem integrated with dam-break disaster loss assessment is built up using GIStechnology. It can provide basic platform for prediction of reservoir danger. Besides,it is valuable for real case application and the methods can be used for other cases.In this paper, firstly, it studies the reservoir earthquake damage assessmentmethod. Secondly, these models including the models of concrete dams damageassessment for important towns dyke water hazard prediction and GIS flood model.Meantime, the theoretical basis for the establishment of these models are focused on.Thirdly, through the requirements and objectives of the system, the overviewanalysis and function design of the system are done. Then, geodatabase data modelis used to manage spatial data and then the principles and methods of dataprocessing are discussed. Based on these analyses, the reservoir damage databasehas been set up. Finally, take the upper region of the Yellow River for instance, a setof reservoir damage forecasting and evaluation system is established and theverification results show that this system is applicable and reliable.
