【摘要】 剪切波速是评价场地土动力特性的重要指标。利用回归方法对天津王庆坨地区实测的剪切波速和相应的标准贯入击数、土层的深度进行统计分析,建立了剪切波速和标准贯入击数、土层深度的定量关系,结果表明土层深度H是当地剪切波速的最佳回归参数,这对天津地区的工程场地的分类和评价有参考价值。更多还原

【Abstract】 Shear wave velocity is an important indicator for evaluation of field soil dynamic characteristic.Through statistical analysis of shear wave velocity and the corresponding standard penetration compaction numberand soil layer thickness measured in Tianjin Wangqingtuo Area with regression method,this paper establishes the quantitative relation between shear wave velocity and standard penetration number and soil layer thickness.The result shows that soil layer thickness H is the optimum regression parameter for the local shear wave velocity,which is a reference for classification and evaluation of engineering field in Tianjian area.更多还原
