摘要
粒径组成是在野外勘测中能直观获取的基本物理性质之一。通过对湖南某线路沿线的花岗岩残积土的物理力学特性进行研究,得到粒径组成与CBR承载比的关系,并选取了代表性的细粒土与粗粒土进行矿物成分及其结构试验,结合物理力学特性分析得到粒径组成可以作为影响花岗岩残积土强度的主控因素。
Grain size distribution is one of the basic physical properties that can be obtained intuitively in field surveys.Combined with the analysis of physical and mechanical properties,the grain size distribution can be used as the main controlling factor of granite residual soil strength through the physical and mechanical properties of granite residual soil study along a line in Hunan Province and obtained the relationship between grain size distribution with CBR bearing ratio,And selected the representative of fine-grained soil and coarse-grained soil for mineral composition and structural testing.
