| 摘 要： | 本文以黄河水下三角洲埕北海区沉积物为研究对象，首次考虑了超孔压随时间的累积和消散效应，得出了相应的的分布曲线。用计算结果评价了粉砂液化的可能性，并给出了液化影响的深度。本文还定量分析了海底土体对波浪周期性荷载的动力响应，并对其不稳定性机制进行了探讨。

| Abstract: | The sediment in ChengBei area of Huang He subaqueous delta is studied in this article. The accumulatingand dissipating effects of excess pore water pressure along with time are considered first and the distribution curves ofexcess pore water pressure along the depth in the soil stratum are gained;the possibility of silt liquefaction is evalu-ated using the computed values and the depth of liquefaction is given. This article quantitatively analyses the dy-namic response of seafloor soil under the cyclic loading of waves and discusses the instable mechanism of soil. |
