An experimental study of cyclic mobility and shear strain history depended on liquefaction of dense sandy ground using a shaking table

A characteristic behavior in the case of liquefaction of the ground is cyclic mobility. Cyclic mobility is regarded as one of the important evaluation items of displacement and deformation when ground liquefaction occurs. This study conducted 1g field shaking table tests for dense sandy ground to consider cyclic mobility. The test results revealed that remarkable cyclic mobility occurred in the region of relatively small shear strain up to 1% to 2% or so if the value of the strain exceeded the past maximum strain and that such a tendency also appeared in the same manner if the shaking cases wereswitched and dissipation of excess pore water pressure was performed between the cases. Additionally, in the case where the shear strain reached about 3%, the results suggested the possible presence of a limit value of strainthat could cause cyclic mobility even if the strain was not exceeded.
