摘要：Random wave loading is the main load needing to be considered when designing offshore structures .According to the features of the waves ,random waves were generated with the linear wave superposition method and random loading trains were recorded .Random wave loading and its corresponding representative wave loading were applied to saturated loose sand samples at different confining pressures using CKC multi-functional stress path triaxial apparatus respectively . The influence of random wave loading shapes on the dynamic characteristics of the sand was examined through applying random loading in ascending and descending order .The experimental results reveal that the changing patterns of pore pressure and axial strain in soil samples under random wave loading are different from those under the representative wave loading ,and the time to reach liquefaction is significantly reduced .Loading sequence of random waves has no obvious impact on dynamic behavior of the sand .
