摘要 采用波流水槽模型试验的方法,研究了规则波和不规则波作用下砂质海床的孔隙水压力响应问题,其中主要考虑不同深度、波高及周期对孔隙水压力的影响,从而得出孔压变化规律。当周期和波高不变时,由波浪引起的孔隙水压力随水深的增加而逐渐减小。同一水深和波高条件下,由波浪引起的孔隙水压力随周期变大而变大;当水深和周期固定时,由波浪引起的孔隙水压力随波高的增加而增加。 The experiment of wave flume model is adopted to study the action of pore water pressure under the sandy seabed induced by both regular and irregular waves. The influences of water depth, wave height and wave period on the pore water pressure are mainly discussed. The rule of pore water pressure responses is achieved. It is shown that the wave period and wave height remain unchanged, the water pore pressure caused by wave decreases as the water depth increases. When the water depth and wave height remain stable, the water pore pressure grows as the wave period lengthens. Under the condition of fixed water depth and wave period, the augmentation of wave height leads to the increase of the water pore pressure.
