摘要
在缺乏强震地面运动观测资料的上海地区用烈度资料建立该区的地震烈度和峰值加速度衰减关系，采用一种新方法——比例系数法计算其标准偏差，并通过实例验证这一关系。
The relations between attenuation of earthquake intensity and acceleration of peak value are presented by using intensity materials in Shanghai area with slight ground motion data. Then a new method(method of proportion coefficient) is used to calculate its standard deviation and demonstrate the relations to the practical case. At last the maximum earthquake intensity in the next hundred years in this region is predicted.
