Abstract
The static and dynamic triaxial shear tests and deformation tests on CSG (cemented sand and gravel) are conducted with different amount of added cementing materials. The mechanical indexes and parameters have obvious increments with mixing of cementing material and accumulation of curing days. However the increments will become mild with further adding of cementing material. The deformation curve of CSG test sample is similar to the curve of sand-gravel sample without mixing with any cementing material, and they both follow the trend of semi-logarithmic decrement law. The dynamic permanent deformation of CSG increases with the increments of confining pressure, consolidation stress and dynamic stress. Thus this deformation still can be calculated using the constitutive model of dynamic residual deformation proposed by Zhujiang Shen Academician.
