摘　　要：对现有高含沙水流理论研究进行了回顾,着重从高含沙水流粘性系数、宾汉极限剪切力、泥沙沉速、流速分布、水流阻力和水流挟沙力等方面进行了成果综述,探讨了现有研究成果的不足和有待改进的地方。本文旨在对高含沙水流理论研究的现状有所认识,对进一步研究高含沙水流的特性具有一定指导意义。This paper is a review and generalization of the present thoeries of hyperconcentrated flows.It mainly expounds the hyperconcentrated flow from the viscosity,Bingham limit yield stress,sediment settling velocity,velocity distribution,resistance to flow and sediment-carrying capacity of the flow,and points out the shortages of the present research.The paper is aimed to have a general acquaintance to the basic theory of hyperconcentrated flows and makes some helps to the further research.
