Abstract

The strength-deformation characteristics of weathered granite soils are determined by the characteristic of bedrock before the weathering and weathering environment. Generally, the degree of weathering is changes with depth and affects the dynamic properties of soil. But there are very few studies of the effect of degree of weathering on dynamic properties of soils in Korea. In this study, dynamic tests were performed with resonant column after preparing the specimens which were remolded with disturbed soils, and the effect of degree of weathering on dynamic properties, such as shear modulus, damping ratio is considered. In addition, the relationships among shear strain, normalized shear modulus(G/Gmax) and normalized damping ratio(D/Dmin) are compared with other studies.

Effect of Degree of Weathering on Dynamic Properties of Weathered Granite Soils

San Diego, California

The strength-deformation characteristics of weathered granite soils are determined by the characteristic of bedrock before the weathering and weathering environment. Generally, the degree of weathering is changes with depth and affects the dynamic properties of soil. But there are very few studies of the effect of degree of weathering on dynamic properties of soils in Korea. In this study, dynamic tests were performed with resonant column after preparing the specimens which were remolded with disturbed soils, and the effect of degree of weathering on dynamic properties, such as shear modulus, damping ratio is considered. In addition, the relationships among shear strain, normalized shear modulus(G/Gmax) and normalized damping ratio(D/Dmin) are compared with other studies.
