【摘要】 本文以1976年唐山Ms7.8地震震害普查数据为基础,选取丰富的统计样本,采用地理信息软件建立地震死亡率、建筑物倒塌率分布图,揭示出唐山地震灾区高震亡率和高倒塌率呈线性集中沿唐山断裂带分布,在河道、古湖泊和砂土液化地区也存在震害髙值区。基于丰富的统计样本,获得了唐山地震死亡率与建筑物倒塌率的非线性关系式。更多还原

【Abstract】 According to seismic damage investigation data of Tangshan Ms7. 8 earthquake in 1976,we select large sample data to establish the distribution maps of mortality and the ratio of collapsing houses in Tangshan earthquake with the method of Geographic Information System and find high mortality and building collapse rate along Tangshan fault zone. There are also high seismic damage areas in the river channels,ancient lakes and sand liquefaction regions. Based on plenty of sample data,we get the nonlinear relationship between the earthquake mortality and the building collapse rate.更多还原
