Abstract：Research purposes: The main researches are done on the heavy tamping property, CBR bearing ratio, expansibility under simulated load of subgrade, unconfined strength, tri-axial shear strength and modulus of compression for the purpose of verifying the feasibility of using red rock as the filling for high-speed railway.
Research results: Through doing researches, the mechanical and physics characteristics of red rock are obtained, such as the maximum dry density, optimum moisture content, shear strength characteristics under saturated and non-saturated conditions, CBR, expansive characteristic and so on. In combination with the experimental research and construction conducted in Dazhou-Chengdu Railway, the analysis of deformation characteristics of high embankment under saturated and non-saturated conditions are made and also the proposals are made to application of red rock as filling materials in filling subgrade.
