摘要
根据汶川8.0级地震震害评估工作的具体实践,探讨了地震灾区分级和灾害程度排序的方法。通过房屋震害系数、强震加速度观测记录、发震构造、地震地质灾害和场地条件、人口分布及伤亡情况等影响因素来确定受灾程度,以烈度区、统计学方法、速报灾情等来确定灾区分级。
According to specific practice in seismic damage evaluation on M8.0 Wenchuan earthquake,methods for classification of seismic disastrous areas and sequencing of disaster degrees are discussed.Disaster degrees are determined with reference to influencing factors as building damage index,observation data of strong seismic acceleration,seismogenic structure,earthquake induced geological disaster,site conditions,population distribution and casualty etc.,and classification of earthquake stricken areas are determined according to seismic area,statistic methods,quick report of disaster conditions and so on.
