Abstract:

The data of damaged houses in Xingtai earthquake,Hebei Province,on March 8 and 22,1966,were collected,and ratios of the collapsed,severely damaged,and moderately damaged a-bode houses in intensit Ⅶ and Ⅸ ares were calculated,respectively. χ²test shows that the prob-abilistic distribution of the ratios of collapsed,severely dameged and mederately damaged houses in indensity Ⅶ and Ⅷ areas fellows a normal distribution.

摘要：

对1966年3月8日和3月22日台地震中的房屋破坏情况进行统计,计算了地震区主要房屋土坯墙房在Ⅳ～Ⅸ度中的毁坏率、严重破坏率和中等破坏率。通过χ²检验得出,Ⅵ度和Ⅸ度区房屋毁坏率、严重破坏率和中等破坏率的分布均服从正态分布。
