Laboratory Flume Studies on Consolidation of Soft Silty Seabed Soil Under Wave Actions
Abstract In this paper, tests on silty soil obtained from the Yellow River Delta under waves were conducted in a wave flume (size: 15(L) ×1.0(H) ×0.5(W), unit: m) to investigate characteristics of its consolidation behaviors. In addition, soil penetration strength was measured with a mini-penetrometer, and variations of pore water pressure were analyzed to study the mechanisms. Results indicated that the sliding interface between the oscillatory layer and the underlying layer would move downwards under another round of wave actions after a period of time&s consolidation under self-weight in static water, while the magnitude of the oscillation would be much smaller than that of the last time. Analytical results of pore water pressure variations clearly illustrated that the liquefaction tended to be initiated in the surface layer and spreading fast into lower layers. The penetration strength data revealed that there was a layer of extremely high strength in the sliding zone, which might be the embryo of the hard crust in the tidal flat of the Yellow River Estuary. All in all, the strength of such silt soil increased unequally along the depth continuously under wave loadings, and the consolidation speed was much higher than that in the static water.
