摘要： 土层的剪切波速值是场地地震效应分析的重要参数指标，还可用来划分场地土类型与建筑场地类别。结合山东省黄河冲积平原地区多个火电厂土的标贯击数和剪切波速值数据，分析了两者之间的相关性，并通过回归分析方法建立了土层标贯击数和剪切波速值的经验关系，为山东黄河冲积平原地区的土层提供了一种简便求解剪切波速的方法。

Abstract: The shear wave velocity of the subsurface soils is one of the important parameters for the site seismic evaluations. This parameter can also be used in the site seismic and well as building classifications. This paper summarizes the standard penetration testing (SPT) N values as well as the shear wave velocity values in several coal burning power stations in Shandong Yellow River Alluvial soils. The regression analyses are performed on the two groups of data. An empirical relationship between the SPT N values and the shear wave velocity is developed for the preliminary design purposes.

Key words: Standard Penetration Test, Shearing Wave Velocity, Correlations, Regression Analysis
