以湖南某高速公路的典型红层泥质粉砂岩为研究对象，通过现场路勘和岩石镜下薄片鉴定，研究了泥质粉砂岩的宏-微观特征，查明泥质粉砂岩的主要矿物组成为石英、斜长石、钾长石、白云母及铁质等．采用压缩变形试验分析了泥质粉砂岩的变形特性，并建立了考虑结构面闭合变形的泥质粉砂岩的弹性本构模型．通过弱面剪切试验分析研究了泥质粉砂岩软弱结构面的变形与强度特性，并提出用剪切刚度来判断其变形与强度特性．

Taking the typical red-bed soft rock belong to Hunan highway as investigative subject,and through field survey and Mirror Image of microsopic, this paper analyzed the macro-micro characteristics of argillaceous sandstone, found out the main mineral composition for quartz, plagioclase, potash feldspar, white mica and iron etc. The compressive strain test analyzed the deformation characteristics, and the elastic constitutive equations of red-bed soft rock, considering the closing of structural surface, are established. The tests of Weak surface shear analyzed and studied the deformation and strength characteristics of argillaceous sandstone＇s weak surface, and put forward to judge its deformation and strength properties with applying shear rigidity. Research results can be applied to the slope of redbed soft rock design and stability prediction.
