液状化した砂の速度依存性に関する室内試験
詳細
A series of laboratory element-shear tests using a torsion shear apparatus was conducted on liquefied sand. The observed variation of viscous shear stress against deviator strain rate revealed that the behavior of liquefied sand is similar to Bingham viscous behavior. Furthermore, it was observed that the Bingham viscous coefficient and viscous shear strength increase with increasing of the mean effective stress. Effects of the relative density of sand, after-shocks, strain history, over consolidation ratio, pore fluids, and fines content of sand on the Bingham viscous coefficient and viscous shear strength were investigated.
