摘要
本文讨论了地震宏、微观震中位置的误差及其主要影响因素，地震波在震中区传播的几何特征、能量衰减规律及其对地表构筑物的影响。提出了在地震宏观考察工作中，根据建筑物在竖向地震作用下产生的震害的力学特征，比较准确可靠地确定宏观震中位置的方法。
The accurW Of epicentral location affectS greatly the arrangenent and inferences Of every aamPect in researchwork. The Study Of errors occurred in both scopic and miCroscislnic epicenttal identifications Shows that they don,t meet the demands Of all apectS in research work. Therefore, the authors put forward a new method of identifing the epicentral location by means of determining thehorizontal and vertical cracks of the eath--surface buildings in the epicentral rigion' The accuracyof identification of the epicentral by this new method is much approved than thst by the usual methods
