| 摘 要： | 细颗粒泥沙在咸水中的絮凝沉降是河流泥沙向海输送过程中在河口区发生的重要现象，是河口拦门沙形成与发育的主要原因之一。本文根据室内模拟试验研究，提出长江口泥沙絮凝静水沉降的二级动力学模式，通过该式求得不同泥沙含量和盐度情况下絮凝沉降的衰减系数，半衰期和平均沉降速率等动力学参数，定量地分析泥沙含量和盐度对泥沙絮凝沉降过程的影响。

| Abstract: | In this paper, based on experimental data, second class dynamic formula about sinking of sand coagulation in stationary water in changjiang Estuary is presented. According to the formula, the authors Ealculate k, t1/2 and w, and analyse in quantity the influence of sediment and salt concentration upon the process of sand coagulation. |
