| 英文摘要 | ABSTRACT The total stress behavior in seabed soil induced by progressive waves was investigated in time sequence through the experiments in a wave flume. The static stress measurements show that the natural deposit seabed retains an initial shear stress that reduces the resistance capacity of shear strength of the soil. The dynamic stress measurements show that, by comparing with seabed surface pressure, the vertical stress, horizontal stress, and pore water pressure are found to have different phase shifts. Such phase shifts strongly affect the duration behavior of the total stresses of the soil and different from the current theories that assume the waves and pressures in seabed are synchronous, the influences on the seabed stability should be taken into account. |
