摘要
系统总结了地震造成的人员伤亡的估算方法,以我国1990-2006年间造成人员伤亡的破坏性地震为数据样本,结合国内几次大地震的震害资料,找出了影响人员伤亡的主要因素,经过函数拟合与回归分析,提出了一个以震中烈度为主要参数,以震级和人口密度作为辅助参数进行修正的人员伤亡预测模型,并利用已有的地震实例进行了模型检验,证明其具有较好的精确性和可靠性。
In this paper,the existing methods for the evaluation of seismic casualty were reviewed.The earthquake casualties＇ data of China from 1990 to 2006 were collected as samples.Combined these data with several representative destructive earthquakes＇ data of China,the main influence factor of earthquake casualty was found out.By function fitting and regression analysis,an earthquake casualty assessment model was put forward,with the epicentral intensity as the key factor and the magnitude and population density as the secondary factors to improve the assessment results calculated from the key factor.Finally,the assessment method presented in this paper is validated by comparing the evaluation results with the real earthquake casualties＇ data.
