摘要

摘要: 根据2004年4月至2009年6月在黄河口潮坪进行的长期现场观测试验结果，研究了黄河泥沙沉积后的固结过程。研究发现：入海泥沙沉积后，强度呈线性增长，孔隙水压力消散曲线符合指数模型，5 d内固结基本完成呈现似超固结状态，沿深度方向强度出现分层现象，并逐渐非均匀化。沉积后的泥沙在自重应力和海洋水动力的长期作用下，土体的强度呈现增长-降低-增长的趋势，沿深度非均匀性提高。首次揭示了黄河入海泥沙的快速固结特性及形成的沉积物强度随时间与空间的非均匀性变化规律。

Abstract: Based on the field tests on the tidal flat of Diaokou delta-lobe from April 2004 to June 2009, the consolidation process of rapidly deposited sediments in the Yellow River Delta is studied. It is found that after the sediment is deposited, its strength increases linearly, and its pore water pressure dissipation curve accords with the index model, and in 5 days, the soil is over-consolidated. Along the depth direction, strength layering phenomenon appeares and comes to be heteropical gradually. And then under the action of the hydrodynamics and the self-weight stress, the soil strength exhibits a trend of growth-reduction-growth, and along the depth, heterogeneity is improved. This study, for the first time, reveals the rapid consolidation properties of the Yellow River sediment into the sea as well as the changing rules of sediment strength with the time and space inhomogeneity.
