基于CPTU试验成果在土体定名中的研究

Study of CPTU test parameters in soil classification

根据孔压静力触探所获得的连续读数,分别绘制摩阻比和修正后的端阻力(Fr—qt)、标准化的摩阻比和标准化的锥尖阻力(RF—Qt)以及侧摩阻力和有效端阻力(fs—qE)的三幅关系图,并结合图确定各层土体的类型;与钻孔取样后的室内试验结果进行对比,得出了一些有参考价值的结论。

According to the continuous reading of the piezocone penetration test（ CPTU）, three figures are plotted about friction ratio and corrected cone resistance（Fr-qt）, normalized friction ratio and normalized cone resistance（RF-Qt ）, sleeve friction and effective cone resistance （fs-qE）. And combined with characteristics of the figures, the type of each soil layer was determined. Then compare with the soil types determined by laboratory test and CPTU, obtained some valuable conclusions.
