| 中文摘要: |
| Cyclic triaxial tests and numerical analyses were undertaken,in order to evaluate the wave-induced pore water pressure in seabed sediments in the Hangzhou Bay.The cyclic triaxial tests indicate that the rate of pore water pressure generation in cohesive soils decreases with time,and the development of the pore water pressure can be represented by a hyperbolic curve.Numerical analyses,taking into account the generation and dissipation of pore water pressure simultaneously,suggest that the pore water pressure buildup in cohesive soils may increase with time continuously until the pore water pressure ratio approaches to 1,or it may decrease after a certain time,which is controlled by drain conditions.These phenomena are different from those in sands.For waves with a return period of 100 a in the Hangzhou Bay,ifthe wave duration is more than 60 h,then the pore water pressure ratio will be close to 1 and soil fabric failure will take place. |
