| 摘 要： | 利用波浪水槽试验,对波浪作用下沙质底床的孔隙水压力响应进行了研究。试验中观测了不同波况条件下自由底床和有抛石基床防波堤的土体孔隙水压力的变化。结果分析表明,土体孔隙水压力受波高、周期、水深、沙粒径、沙床厚度的影响较大;建堤后,底床中的孔隙水压力会增大,有效应力降低,对防波堤的稳定性造成严重影响。 |

| Abstract: | A flume test model is used to analyze the variation of pore water pressure and the behavior of different areas in sand bed of breakwater under different wave conditions.Some phenomena obtained from the experiment suggest that wave height,period,water depth,sand size and sand depth are the more important factors influencing the pore-water pressure;and the pore-water pressure around breakwater is increased after it built.Effect stress is reduced,and it cause serious influence on the stability of the breakwater. |
| Keywords: | Flume test Pore-water pressure wave rubble mound breakwater sandy seabed |
