| 摘 要： | 我国是地震多发的国家之一，其中破坏性地震的发生频率也相对较高。伴随着我国经济的高速发展与城市化进程的加快，地震风险意识的提高以及国家对地震应急救援能力的更高要求都促进了对地震灾害评估方法的研究。其中地震人员伤亡评估方法更是灾情预测的重中之重，然而我国大部分历史地震都发生在西部，已有的地震人员伤亡评估方法也是基于西部历史地震资料统计分析得出的。人口密度更高和经济更为发达的东部地区，一旦遭遇破坏性地震，其灾害程度将远超西部，因此现有方法已不能很好地满足东部地区的地震预防和应急救援决策需求。需要结合东部地区的特点修正适用于东部地区的地震人员伤亡评估方法。本文初步分析了东西部影响地震人员伤亡的影响因素，对比主要区域差异，指出东西部地区建筑的抗震性能差异主要体现在城市自建房屋的比例和农村主要结构类型占比上。给出了东部地区地震人员伤亡评估的修正系数，并通过算例分析了其适用性。

| Abstract: | China is one of the countries with frequent earthquakes, and the frequency of destructive earthquakes is relatively high. With the rapid development of China’s economy and the acceleration of the urbanization process, the improvement of the awareness of earthquake risk and the higher requirements of the country for the ability of earthquake emergency rescue have promoted the research on the methods of earthquake disaster assessment. Among them, the assessment method of earthquake casualties is the most important one in disaster prediction. However, most of the historical earthquakes in China occur in the west, and the existing assessment method of earthquake casualties is also based on the statistical analysis of historical seismic data in the West. In the eastern region with higher population density and more developed economy, once a destructive earthquake occurs, its disaster degree will be far beyond the western region, so the existing methods can not meet the needs of earthquake prevention and emergency rescue decision-making in the eastern region. It is necessary to modify the assessment method of earthquake casualties suitable for the eastern region according to the characteristics of the eastern region. Comparing the major regional differences between China’s east and west, the influencing factors of earthquake casualties are analyzed. And the seismic performance differences of buildings focus on the proportion of self-built houses in cities and the proportion of main structural types in rural areas.The correction coefficient of earthquake casualty assessment in the eastern region is given, and its applicability is analyzed by some examples. |
