长江中游陆溪口水道直港进口挖槽疏浚工程效果试验研究

Model test of dredge-cut engineering in Zhigang entrance on the Luxikou waterway on the middle reaches of the Yangtze River

在对长江中游陆溪口水道河床演变分析的基础上,通过模型试验对其航道整治工程中尚未实施的直港进口挖槽疏浚工程在目前河势条件下实施的可能性和工程效果进行研究。研究结果表明:设计的直港进口挖槽疏浚工程难以改变其枯水碍航局面,更难以达到将其整治为主航道的目的。

Based on the analysis of the bed evolution of Luxikou waterway on middle reaches of the Yangtze River,we studied the implementation possibility and engineering effect of Zhigang entrance dredge-cut engineering through the model test.The results show that the dredge-cut project designed in Zhigang entrance can＇t prevent the obstruction to navigation in the low water period,and it is more difficult to attain the aim of changing it to the main channel.
