城市地震灾害风险评价方法研究

风险管理研究已成为防灾减灾工作从“被动救灾”到“主动预防”转化的热门课题。本文回顾了地震灾害风险评价研究进展,指出了现有评价方法的不足。提出了基于地震小区划的城市地震危险性评价方法、基于城市用地类型的城市地震易损性评价方法以及基于专家打分法的城市防震减灾能力评价方法。最后设计了城市地震灾害风险评价流程,并给出了城市地震灾害风险区划算法。

Research on Method of Urban Earthquake Disaster Risk Assessment

The risk mamagement research has became a hot subject in the domain of disaster prevention and mitigation as the works changed from "passively relieve disaster" to "active prevention" in recent years.In this paper,the research grogress of the earthquake disaster risk assessment is reviewed,and the shortcomings of some precent methods are pointed out also.Then,the method of urban earthquake hazard assessment based on the earthquake microzonation,the method of seismic vulnerability assessment based on urban landuse types,and the method of disaster prevention and mitigation capacity assessment based on expert scoring are presented.At last,the flow of the urban earthquake disaster risk assessment is designed,and its arithmetic is given.
