板结粉沙运动规律的研究

The movement characteristic of consolidated silt

本文对黄河埕岛地区的＂铁板沙＂起动特性进行了研究，通过理论分析及试验研究，根据板结粉沙的特点，提出了＂板结力＂的概念，给出了其起动现律表达式．依据功率模型的概念，通过试验及理论分析，给出了波流共同作用下板结粉沙的输沙率公式．

The results of theoretical analysis and experimental study on the movement of consolidated silt due to free settling are presented in this paper. A new concept-' consolidation force' is suggested and the expression of the threshold velocity is deduced. Based on the power model and experimental data the formula of specific silt transport under the action of current in combination with wave is given.
