摘要
根据徐州地区大量的粘性土标准贯入试验及土工试验资料,基于数理统计理论,采用回归分析方法研究了标贯击数与物理力学指标间的相关关系,拟合了相应的回归方程。结果表明,粘性土物理力学参数与标贯击数具有高度线性关系,利用标贯击数确定粘性土物理力学参数具有较高的可靠性。研究成果可为建立地区经验公式提供基础性资料。
According to a large number of standard penetration test and geotechnical test data for clay soil in Xuzhou area,based on mathematical theory,the relationship between standard penetration blow counts and physical mechanical indicators of clay soil is studied using regression analysis method and fitted with the corresponding regression equation in this paper.The results show that there is a highly linear relation between physical mechanical parameters of clay soil and standard penetration blow counts.Therefore,physical mechanical parameters of clay soil can be determined by standard penetration blow counts with higher reliability.The results can serve as a reference for establishing regional empirical formula.
