长江下游“三沙”航道整治工程表面流速流向观测

The Observing of the Surface Current Velocity and Direction in Three Shoals Renovating in Yangtze River

简要介绍了长江下游“三沙”航道整治工程中为了掌握双锏沙横流和如皋沙中汊在刘海沙水道的汇流情况,在福姜沙左汊道→双锏沙→浏海沙水道间进行了表面流速流向观测,并对测量成果和航迹线图进行了初步分析,从而为保持双锏沙的稳定、保证如皋沙群水道的长久贯通提出了一些工程措施。

The paper introduces the work of surveying the surface current velocity and direction in the three shoals renovating in the Yangtze River. On the analysis of the surveying result, the author gives some advice to ensure the stability of the Shuangjian shoal and the channel of the middle branch of the Rugao shoal.
