摘要
简要描绘了粘性泥沙浑液面沉降的物理图景,概括和分析了国内外学者在粘性泥沙浑液面沉速公式方面的研究成果,并指出了所存在的问题,在此基础上展望今后的研究工作。
The advances in the research of the settling velocity of the interface between clear supematant water and turbid suspension of cohesive sediment are reviewed in this paper. First, the phenomenon and the mechanism of the interface in the sedimentation of cohesive sediment are brought out. Then two kinds of research results on the interface settling velocity are reviewed, namely experimental formulas and theory or semi-theory formulas. For each kind of formula, the different forms and ways of the foundation of the formula are analyzed by different researchers and the existent problem.s and limitations are pointed out. At last, the future research prospect of the settling velocity of the interface is proposed in this paper.
