Dynamic Shear Modulus of Soft Silt

This paper presents the geotechnical properties of soft silt obtained from the Greater Shanghai Region of the People\u27s Republic of China. Fundamental correlations of shear modulus, damping ratio, shear stress, shear strain with varying consolidation pressures are determined in the laboratory by cyclic simple shear tests. A comparison is made between laboratory test results, in situ cross-hole test results and the building code data proposed by the Shanghai Municipal Bureau. Finally, a comparison of the laboratory data on Shanghai silt with other published data on sands and clays is presented and discussed
