摘　　要：本研究以粘土质砾为研究对象,通过抗剪强度试验,分析了其抗剪强度特性,并系统研究了质量含水量、粗细骨料配比的影响规律。其中,粘土质砾的抗剪强度参数与质量含水率均呈现出负相关,但随着细骨料含量的变化,粘土质砾的抗剪强度参数呈现出先增后减的变化。最后,通过多元线性回归模型拟合抗剪强度参数与含水率和细颗粒含量间的关系,并验证了质量含水率和细骨料含量两个因素对粘土质砾抗剪强度的显著影响。This study takes clay gravel as the research object,analyzes its shear strength characteristics through shear strength tests,and systematically studies the influence of mass moisture content and coarse to fine aggregate ratio.Among them,the shear strength parameters of clay gravel show a negative correlation with the mass moisture content,but with the change of fine aggregate content,the shear strength parameters of clay gravel show a first increase and then decrease change.Finally,the relationship between shear strength parameters and moisture content and fine particle content was fitted using a multiple linear regression model,and the significant effects of two factors,mass moisture content and fine aggregate content,on the shear strength of clay gravel were verified.
