Research on Physical and Mechanical Parameters of Clay Based on Geotechnical Tests

为探究黏土物理力学参数之间的相关性,解决实际工程中测定某些黏土基本物理力学参数时面临的周期长和成本高的问题,文章取某岩土工程项目中的黏土进行了相关土工试验,测定了该黏土的基本物理力学参数,分析了各物理参数之间的相关性。结果表明,该黏土各物理参数之间的相关性较好,相关系数均在0.92以上。同时,通过回归分析得到了该黏土各物理参数之间的定量关系公式,并通过与理论公式进行对比,发现拟合分析得到的回归方程接近理论公式,说明文章得到的各物理力学参数之间的定量关系可为实际工程中的黏土物理力学参数的研究提供一定的依据和借鉴。

In order to explore the correlation between the physical and mechanical parameters of clay and solve the problems of long cycle and high cost when measuring certain basic physical and mechanical parameters of clay in practical engineering,this study conducted relevant geotechnical tests on clay in a certain geotechnical engineering project,measured the basic physical and mechanical parameters of the clay,and analyzed the correlation between various physical parameters.The results indicate that there is a good correlation between the physical parameters of the clay,with correlation coefficients above 0.92.Meanwhile,through regression analysis,a quantitative relationship formula between the physical parameters of the clay was obtained.By comparing it with the theoretical formula,it was found that the regression equation obtained from the fitting analysis was close to the theoretical formula,indicating that the quantitative relationship between the physical and mechanical parameters obtained in the article can provide a certain basis and reference for the study of physical and mechanical parameters of clay in practical engineering.
