Experimental study on dynamic shear modulus and damping ratio of remolded loess

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Dynamic shear modulus and damping ratio are two important parameters to characterize the dynamic characteristics of soils. In this paper, the influence of dry density and consolidation pressure on dynamic shear modulus and damping ratio of remolded Guyuan loess is studied by resonant column tester.
