摘要
以昆明红黏土为研究对象,分别研究在不同粒径级配和含水率的影响下,原状与重塑红黏土剪切特性的差异性。结果表明,在不同粒径级配和含水率下,原状与重塑红黏土在剪切特性方面有着明显差异。根据试验结果,基于数理统计分析,得出黏聚力和内摩擦角在上述影响因素下的量化模型,并通过所得量化模型进行数据修正,在一定程度上提高了原状土样的物理力学性质试验结果的准确性。
Taking Kunming red clay as the research object,the differences in the shear characteristics of the undisturbed and remolded red clay under the influence of different particle size gradations and moisture content are studied.The results show that there are obvious differences in the shear characteristics of the undisturbed and remolded red clays under different particle size gradations and moisture content.According to the test results,a quantitative model of cohesion and internal friction angle under the above influencing factors is obtained based on mathematical statistical analysis,and through the obtained quantitative model for data correction,the accuracy of the test results of the physical and mechanical properties of the undisturbed soil sample is improved to a certain extent.
