地震人员伤亡的动态评估

Dynamic Assessment of Seismic Casualties

引入初始人员伤亡矩阵的概念 ,确定老旧民房、砌体结构、混凝土框架结构的初始人员伤亡矩阵 .在综合考虑初始伤亡状态、被困环境、被困时间、人员素质等因素的基础上 ,建立了地震人员伤亡的动态评估方法 .使用该方法对 1 996年丽江地震的人员伤亡进行动态测算 。

A concept of initial casualty matrix was led into the assessment of seismic casualties; and the initial casulty matrix of old folk house and masonry structure and RC frame structure were determined. Considering such factors as state of initial casualties, trapped environment, trapped time and physical status of casualties, a method was formed for dynamically assesing seismic casualties; and had been used for evaluating the casualties caused by 1996 Lijiang earthquake. A comparison between post earthquake statistics and analytical results indicates good agreement.
