场地土分类的模糊性分析

Fuzzy Analysis of Site Ground Earth Classification

论述了场地土的划分类别及“近震”和“远震”定义的模糊性、场地土特征周期和有关动力特征参数的综合评定计算式，最终论述了“中震”的概念及相应参数。

The paper deals with the sorts of site ground earth classification, the fuzzy feature embodied in definitions of both near earthquake and remote earthquake, site earths characteristic period and the evaluation formulas comprehensionally in calculation of the relative dynamic characteristic parameters. Finally it also discussed the definition about the middle places earthquake being concerned with its parameters in respondence.
