【摘要】 对于昆明呈贡新区大量实测钻孔剪切波速,在通过土层类别划分研究后,采用统计回归方法分析了场地土层剪切波速相关特征,拟合剪切波速与土层深度之间关系,认为将场地土分四大类后可得到较好拟合效果,剪切波速与深度关系采用幂函数表达较为适宜.最后对呈贡新区等效剪切波速进行计算并据此进行分类划区,分析了该区等效剪切波速的平面分布特征.更多还原

【Abstract】 This paper measures large quantities of borehole shear wave velocity in Chenggong,the new district of Kunming.After a study about the classification of the soil,the author uses the statistics regression method to analyze the features of site soil shear wave velocity,fitting the relationship between shear wave velocity and soil depth.Results suggest that the soil will be better fitting when the site soil was divided into four categories,and that expressing shear wave velocity and depth relation by a power function is relatively more appropriate.Finally,based on the calculation of equivalent shear wave velocity in Chenggong,the classification of this district is undertaken,and the distribution characteristics of the equivalent shear wave velocity in this district is illustrated.更多还原
