利用潮汐动力整治河口碍航浅滩的试验研究

Use of Tidal Power in Estuarin Navigation Channel Regulation

根据珠江三角洲八塘尾河口段的河道形态及潮流特性 ,在对潮汐动力可利用性探讨的基础上 ,提出了碍航浅滩整治的工程方案 ,并进行了冲淤试验 .试验成果表明 ,采用鱼嘴工程利用潮汐动力不仅解决了出海航道碍航问题 ,而且使洲尾开挖区航道内回淤量明显减小 ,是一种行之有效的整治途径 .应指出 ,鱼嘴工程方案布设和试验是初步探讨性的 ,对于整治工程结构调整和优化组合 ,还需进行深入试验研究 .

According to the shape of the river course and the tidal characteristics of the tidal flow at Batangwei in the Pearl River Delta,a navigation channel regulation project is put forward in this paper. Tests show that the tidal power can be used to dredge the waterway and to decrease deposition in the waterway. It is pointed out that the design of the project needs further study.
