粉砂质海岸泥沙淤积的研究

Study on Silting of Silty Sand Goast

本文从水流动力学及泥沙运动学的基本原理出发.分析了粉砂质海岸泥沙运动的特性,指出,粉砂质海岸的泥沙运动兼有悬移和推移两种形态,悬移与推移运动强度既与水流强度有关.也与泥沙的组成有关,本文从水流的能量分配入手,重点阐述了二者的相对量,同时,给出了粉砂质海岸淤积量的计算公式.

In this paper, proceed from the basic principle of flow dynamics and silt kinematics, by way of specific property analysing of silt movement on silty sand coast, it is pointed out that silt movement on silty sand coast are both in the patterns of suspension and deslodging. The strengths of suspension and deslodging movement relate to flow strength and silt composition, starting with the flow energy distribution, the relative value of that is set forth, at the same time, the calculating farmula of silting on silty sand coast is given.
