【摘要】 利用文献［１］的公式推导出不同烈度区的灾害损失率和地震总损失估计公式，同时还对抗震加固的合理性进行了讨论．从而将地震经济损失估计结果与理论烈度衰减关系联系起来，可以使人们进一步理解灾害损失的实质．另外还计算了一些实际震例以验证这一理论估计的合理性．更多还原

【Abstract】 n this paper,the theoretical formulas of the damage rate of seismic hazard and the total damage evaluation were deduced by using the formula of document ,moreover,the rationality of earthquake resistance reinforcement was discussed,finally,the rationality of the theoretical evaluation was tested by calculating some actual cases.This study will conduce to deeply understanding the essence of hazard damage through the ralationship between hazard evaluation and theoretical intensity attenuation.更多还原
