现有地震灾害评估系统多以设定地震的方式进行震害评估,无法满足地震灾害风险评估中按照不同烈度对整个行政区域进行地震灾害评估的业务需求,本文以现有计算模型为框架、以ArcEngine 为GIS开发平台、采用C/S结构进行基于居民地的不同烈度下地震灾害评估系统设计。系统以居民地为评估单元,根据选择的评估区域,按照Ⅵ度、Ⅶ度、Ⅷ度、Ⅸ度、大于等于Ⅹ度5个级别分别进行地震灾害建筑物损坏情况和人员伤亡评估,结果可为各级政府及相关部门进行区域地震风险评估、地震灾害预评估提供技术支持。

The previous earthquake disaster assessment system mostly carries out the earthquake disaster assessment in the way of setting earthquakes,which cannot meet the business needs of the earthquake disaster assessment of the entire administrative region with different intensities in the earthquake disaster risk assessment. In this paper,taking the previous calculation model as the skeleton,based on the GIS platform with ArcEngine,we apply C/S structure to design the seismic disaster assessment system under different intensity based on residential area. The system takes the residential area as the evaluation unit. For each selected assessment area,the system evaluates the damage of buildings and casualties of earthquake disasters in the five grades of Ⅵ,Ⅶ,Ⅷ,Ⅸ and ≥Ⅹ. The results can provide technical support for governments at all levels and relevant departments to carry out regional earthquake risk assessment and earthquake disaster pre assessment.
