河床粗化研究的回顾及展望

本文综述了已有河床粗化的研究成果,包括河床粗化类型;床面可动层;粗化层的形成机理、级配计算、稳定性判别及河床极限冲刷深度的计算等,并用水槽及天然资料对粗化层级配计算方法作了简要评述,指出了尚有待改进的地方及今后着重开展的工作。

Review and Respect of Research on Armoring of River Beds

In this paper , the research results , including the types of armoring of river beds, the active layer , the formed mechanism of armor layer,the charactaristics the calculation of size distribution,the stability criterion and the calculation of the maximum depth of scouring are discribed and the calculate methods of size distribution of armor layer is briefly commented on with obtained experiment and measured data. The way to further impovements and mportant works on armoring of river beds is also discussed.
