【摘要】 本文的目的是要利用我国极其丰富的历史地震烈度资料，为工程建设提供合理的抗震设防依据。为此选择历史地震史料比较丰富的山西中部地区及地震活动比较强烈的四川攀西地区进行地震区划的实验研究。利用场地影响烈度的统计特性，对实验区内各控制点的影响烈度目录进行极值统计分析，得到平均重视期为５００年和１０００年的地震影响烈度区划图。其结果表明：①在历史地震资料比较丰富的地区，可以利用场地影响烈度的统计特性来编制具有概率含义的地震烈度区划图；②在建立历史地震影响烈度目录时，必须核实破坏性地震对各控制点所造成的高烈度影响；③在确定统计时段时，应充分考虑烈度资料的完整性和区域地震活动的非均匀性；④在确定影响烈度上限时，要根据各控制点所处的地震构造环境，并结合历史上遭遇过的最大影响烈度值而综合判定；⑤经过比较发现，山西中部地区平均重视期为５００年，攀西地区平均重视期为１０００年的地震影响烈度区划图与新的＂中国地震烈度区划图（１９９０）＂在分区形态上大体相近，个别地段有差异，也各有其合理性。本文与新的＂中国地震烈度区划图（１９９０）＂，在基础资料和分析方法上都不尽相同，但其结果的相似性说明，两者均从不同的角度反映了地震危险性的区域特?更多还原

【Abstract】 The purpose of this paper is to provide reasonable basis of earthquake resistance and protect for engineering projects using very wealthy intensity data of historical earthquakes in China. A experiment research on seismic regionalization is made through selecting two regions, middle Shanxi with a wealth of historical earthquake data and Panxi, Sichuang with high seismicity in this connection. Using statistical characteristics of response intensity at different sites, statistics and analysis of extrema in response intensity catalogues of every control sites in experimental rengions are made and seismic regionalization map of response intensity with average reappearing period of 500 years and 1000 years is obtained.The results show that 1. in the region with a wealth of historical earthquake data, seismic intensity regionalization map with probabilistic implication can be complied using statistical characteristics of response intensity at different sites;2.in setting up response intensity catalogue of historical earthquakes, high intensity influence of destructive earthquakes on every control sites should be examined;3.in determining statistical time interval, intergrity of intensity data and heterogeneity of regional seismicity should be taken fully into accout; 4.the upper limit of response intensity should be evaluated comprehensively on the basis of seimotectonic environment at every control sites and in combination with maximum response intensity value encountered in history;5.it is found,from comparison,that seismic response intensitymaps for the average reappearing periods of 500 years in middle Shanxi and 1000 years in Panxi region are about the same in regionalizing form as new Seimic Intensity Regionalization Map in China(1990), and there are differences in some segments between the two maps but it is reasonable for each map.The similarities between results obtained by the paper and new Seismic Intensity Regionalization Map(1990) show regional feature of seismic risk reflected.by the two ways from various angles using different basic data and analysis methods.更多还原
