摘要
针对波浪荷载作用下粉质海床的动力响应问题,结合波浪槽模型试验研究的结果,提出了一种粉质海床在波浪作用下超静孔隙水压力增长的数值分析方法。计算结果表明:该方法能较好地拟合试验数据,揭示粉质海床孔隙水压力发展的机理,能运用于海床液化势的评价分析。
Aimed at dynamic problem of wave-induced response in silty seabed, and combined with the results ot model test m wave flume, numerical analysis method based on wave action is carried out to calculate the increment of excess pore water pressure. Numerical results indicate that the method is in good agreement with those obtained from laboratory test. It can be used to clarify the developmental mechanism of pore pressure in silty seabed, and to evaluate the liquefaction potential of the seabed.
