【摘要】 本文对1969年以前发生在中国境内的5级以上的地震震害进行了总结。提出了历史震害分布规律及震害出现次数与烈度曲线函数关系,给出震级与震害最大距离的关系公式。这些规律和公式,对震害预测和烈度小区划有一定参考价值。 我国有丰富的地震灾害记录,但至今还散落在各种地震文献之中,如果把这些资料进行整理,用之于生产建设,将有一定的实际意义。 据此目的,本文对公元前1177年至1969年间发生的地震进行了总结,并着重研究了震害情况。更多还原

【Abstract】 It is concluded that the surface manifestation of the earthquake disaster was associated with 620 of 2054 shocks that appeared in China in a span of time from 1177 B. C. to 1969. The earthquake disaster is represented by landslip, ground fissure, ejected water and sandblow and the like.Viewed from data in this regard, it can be found that the distribution of the earthquake disaster is characterized by regionalization, segmentation and reproducibility. Where an intensity is up to Ⅵ, the earthquake disaster may be distinguished. With an intensity more than Ⅸ, there would be very a possibility for an earthquake to lead to a severe damage. An earthquake magnitude can be shown to be proportional to a distance of the segment where the earthquake damage was noticed from the epicenter. This can be written as a formula and this is a significant reference to prediction of the earthquake disaster, seismic mierozoning and earthquake resistance and the like.更多还原
