| Abstract: | Cyclic behavior of Dashihe tailings sands was investigated by means of cyclic simple shear apparatus. The following relationship were studied: variations of dynamic shear modulus ratio and damping ratio with shear strain,variations of cyclic stress ratio,cyclic shear strain and residual pore pressure with cycle,variation of post-liquefaction shear stress with shear strain. |
