黄河三角洲地区土层剪切波速与标贯击数关系统计分析

Statistical Analysis Of the Relationship Between The Soil Shear Wave Velocity And The Number Of Stand Penetration Test In The Yellow River Delta

根据黄河三角洲地区大量的钻孔资料,利用指数回归法和线性回归法对土层剪切波速与标贯击数的关系进行了统计分析,认为黄河三角洲地区土层剪切波速(Vs)与标贯击数(N)符合指数关系,并给出了相应的回归方程和适用埋深,便于特殊情况下获取剪切波速。对比分析了其他地区的回归方程,认为回归方程具有地区差异性,差异性原因可能与土层结构、颗粒组成、埋藏环境、形成时代等有关,尚需深入研究。

According to a large number of drilling data in the Yellow River Delta, statistical analysis of relationship between the shear wave velocity of soil layer and standard penetration test blow count was done by exponential regression and linear regression between, and it was suggested that the soil layer construction and the standard penetration test blow count in the Yellow River delta are in accordance with the exponential relationship, and the corresponding re- gression equation and the application of the buried depth was given in order to get shear wave velocity for special case. The regression equation of other regions is analyzed, and it was suggested that regression equation are with regional differences, and the reason may be related to the soil layer construction. Grain Composition. burial environment, etc. and it was still need further research.
