摘    要:根据大量的钻孔P-S测井实测数据分析归纳了昆明盆地第四系粘性土及砂性土层的剪切波速值及其特征。利用相关分析方法给出了各土层剪切波速Vs与标贯击数N的回归方程。探讨了土层埋深等因子时剪切波速的影响,给出了剪切波速Vs与土层埋深的回归方程。

关 键 词:第四系土层  粘性和砂性土  剪切波速  标准贯击数  土层埋深  相关分析

Abstract:According to large amounts of in situ P-S logging data, the relationship between shear wave velocity and other physical properties of the clayey and sandy soils in the quaternary formation of Kunming Basin are summarized. With the aid of linear and non-linear correlation analyses, the regression equation of shear wave velocity and the standard penetration test N value (SPT-N value) are given here. The influence of ground depth to the shear wave velocity is discussed and the trend of shear wave velocity with the depth is also clarified.
Keywords:quaternary formation    clayey and sandy soils    shear wave velocity    SPT-N value    ground depth    correlation analyses
