Abstract:

The ratio of collapsing houses by Tangshan earthquake was determined by sampling from aero photographies which were taken after shock. Analysis of mortality shows that the death percentage related to collapse of houses is more than 80%. Based on the fact that the death is mainly caused by collapse of houses, the regression curve of mortality and the ratio of collapsed houses by Tangshan earthquake is formulated. This curve can be used to rapidly estimate the death after shock by using the phase of damaged houses which can be surveyed from aero photographes.

摘要：

运用震后航空像片抽样统计了唐山地震的房屋倒塌率,分析了造成人员伤亡的主要原因是房屋毁坏。据此,建立了地震人员伤亡率与房倒率的回归方程,该方程可用于震前人员伤亡预测和震后快速粗估。
