摘要
场地类别是确定场地地震动参数的依据,其分类标准的不同直接影响地震动参数的确定。在详细阐述了五种场地类别分类方法和所采用的分类指标基础上,首先采用中、美、欧、日、陈国兴法对松原地区的场地进行了场地类别划分,并对比分析了所得到的结果,其次采用最小二乘法建立Ⅱ、Ⅲ、Ⅳ类场地的拟合公式,通过拟合公式将界限值转化为V_(S20)、T_(S)转化为T_(G),探讨了中美欧日场地分类方法以及陈国兴法的区别与联系。研究结果表明,陈国兴法对我国现行抗震规范场地分类方法的改进有参考价值。
The classification of ground motion is the basis for determining ground motion parameters,and the different classification standards directly affect the determination of ground motion parameters.Based on detail elaborates the five venues category classification method and adopted by the classification index,based on the first use,the United States,Europe,Japan,bosco chan method for matsubara region area for the site classification,comparison and analysis of the results,followed by least squares method is adopted to establish theⅡ,Ⅲ,Ⅳfitting formula of the site,Through V_(S30)transformation V_(S20)and T_(S)transformation into T_(G),this paper discusses the differences and connections between Chinese,American,European and Japanese site classification methods and Chen Guoxing method.The results show that the Chen Guoxing method has reference value for the improvement of site classification method in China's current seismic code.
