长江下游张家洲水道6 m水深航道治理措施
|
摘要
为实现武汉至安庆段6 m水深初通,需对该河段进行航道整治。张家洲水道为其中一段,是长江中下游重点碍航浅滩水道之一。在已建航道整治研究的基础上,依据张家洲水道原型观测基础资料,分析6 m水深航道条件及其变化趋势,提出整治思路及原则。同时结合物理模型试验,对本水道演变趋势进行预测,并开展整治方案效果试验研究。成果表明,随着整治方案的实施,本水道6 m水深航道条件基本能达到,仅少数不利水沙年份需辅以一定量的维护性疏浚。
In order to realize the initial passage of 6 m water depth on the Wuhan to Anqing section of the Yangtze River main line,waterway regulation is needed. Zhangjaizhou waterway is one of the important shallow channels in the middle and lower reaches of the Yangtze River. Based on the research on the regulation of built waterway and according to the basic data of prototype observation of Zhangjiazhou waterway, we analyze the condition of 6 m-depth waterway and its changing trend in depth,and propose the regulation idea,principle and parameters. Combining with the physical model experiment to study the regulation,we predict the evolution trend of the watercourse and carry out the effect experimental study on the regulation program. The research results show that,with the implementation of the regulation program, the condition of the 6 m-depth waterway of the watercourse can be basically achieved.
