摘要
从危险性评价、易损性评价以及防灾减灾能力评价3个方面阐述了城市地震灾害风险评价内容。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。
This article discusses risk assessment of urban earthquake disaster, which includes risk assessment, vulnerability assessment, disaster prevention and mitigation capacity assessment. Firstly, the article reviews the research process on earthquake risk assessment, and points out shortcomings of these methods. Secondly, the article presents the urban earthquake risk assessment based on earthquake microzonation, vulnerability assessment based on land-use type and disaster prevention and mitigation capacity assessment based on expert scoring. At last, the flowchart of risk assessment of urban earthquake disaster is designed, and zonation arithmetic of risk region is showed
