为了定性了解河口泥沙运动的一些规律性,我们一方面可以从实测资料进行一系列分析来获得这方面的知识,另一方面也可以从理论的角度来进行充分的探讨。在实测资料缺乏的情况下,那就只能依靠理论分析来获得河口泥沙的运动规律性知识。本文从两相流体流动的观点出发来讨论河口泥沙的运动和淤积等问题。文中对两个特殊的情形进行了讨论和计算。一个是对一维矩形断面河道进行了简化理论分析。另一个是对某河流某一实际河段进行了计算,并和某测站实测的流量和泥沙浓度的过程线进行了比较,结果是令人满意的。
In order to qualitatively understand some regularities of sediment movement in the estuary, we can obtain a series of analyzes from the measured data on the one hand, and on the other hand, we can make a full discussion from the theoretical point of view. In the case of lack of measured data, it can only rely on theoretical analysis to get the knowledge of the regularity of the movement of estuarine sediment. In this paper, from the point of view of the flow of two-phase fluid to discuss the estuary sediment movement and deposition problems. Two special cases are discussed and calculated in this paper. One is a simplified theoretical analysis of a one-dimensional rectangular section of the river. The other is to calculate the actual river section of a river, and the measured flow and sediment concentration of a station measured the process line, the result is satisfactory.
