摘    要:以街区和自然村为样本,通过唐山震害航片对1942个样本进行房屋倒塌率判读和分区统计,建立了房屋倒塌条烈度相关模型,分析了不同烈度区房倒率的频度展布特征。其模型可为大震应急及震害损失快速评估时烈度评定提供定量标准,频度分析结果可为震害预测提供量化依据

关 键 词:唐山地震  房屋倒塌率  烈度  相关分析

CORRELATION ANALYSIS OF PERCENTAGE OF COLLAPSING HOUSES AND SEISMIC INTENSITY OF TANGSHAN EARTHQUAKE
Abstract:Percentage of collapsing houses by Tangshan earthquake was interpreted by sampling fromaerophotographes which were taken after shock. The regression curve of perectage of collapsinghouses and seismic intensity was formulated by using 1942 samples with respect to the samplingsize of urban street and suburban village, which can be used to determine the intensity in fast es-timation of damage and emergency activity after shock.The frequency of perectage of collapsinghouses in each intensity was also calculated,which provides a numerical method for eatimation ofearthquake losses.
Keywords:Tangshan Earthquake  Collapsing houses percentage  Seismic intensity  Correlation analysis
