| 摘 要： | 利用不同波高条件下的波浪水槽试验,对现行黄河水下三角洲粘质粉砂底床的性态变化进行了研究.试验中观测了底床土体孔隙水压力的变化和扰动破坏区与未扰动破坏区之间在波浪作用下的性态差异.结果分析表明,土体孔隙水压力受波高要素影响较大;扰动破坏区含水量减小和容重增加现象比未扰动破坏区明显.在扰动破坏区经波浪长时间作用后形成凹坑塌陷,此结果对认识黄河三角洲上凹坑塌陷的形成过程有借鉴意义.

| Abstract: | A flume test
model is used to analyse the variation of pore-water pressure and behavior of different
areas in clay-silt bed under different wave conditions. Some phenomena obtained from the
experiment suggest that hydrodynamic features, in particular wave height, are among the
more important factors influencing the pore-water pressure, and the variation of
water-content and soil density in disturbed areas is more obvious than that in undisturbed
areas. |
