| 1 | An Experi mental Study on Wave-Induced Dynamic Stresses in Seabed显示文摘A series of hydraulic model tests with horizontal movable seabed under regular wave actions have been carried out to investigate the dynamic interactions between water waves and seabed soil.Seabed dynamic stresses from experiments are found to differ from theoretical results.The response of p 0 in permeable seabed has a small decay and phase shift to the nonlinear wave actions,and the dynamic stresses,σ v /p 0 ,σ h /p 0 and u/p 0 ,contain different phase shift characteristics.Such phenomena will strongly affect the dynamic stress path in seabed.If the phase shifts ofσ v andσ h are neglected,the stress path will become a straight line;otherwise,it will become an elliptical curve.In phase shift cases,the long axis of the p-q diagram will be shortened when the depth increases,and the short axis will become longer when the phase shift increases.For the p′-q′diagram,the larger the phase lag of u,the longer the short axis.Relative results offer useful information for the analysis of seabed stability. | S.C.Chang L.K.Chien J .G.Lin Y.F.Chiu | 2006 | China Ocean Engineering2006，20，1： | 0 |
