【摘要】：藕池口水道位于长江中游下荆江首端,属顺直放宽的喇叭型河道,河床演变复杂。在总结该水道演变规律的基础上,结合一期工程建设效果,综合分析河道近期变化特点,并对该水道的演变趋势进行预测。分析表明,一期工程实施后,藕池口水道进口右边界和过渡段航槽得到了基本控制,水道近期的滩槽格局得到稳定,应抓住当前有利时机实施后续工程,巩固已建工程效果,进一步改善航道条件。
[Abstract]:The lotus root pool mouth water channel is located at the first end of the lower Jingjiang River in the middle reaches of the Yangtze River. It is a straight and relaxed loudspeaker channel and the river bed evolution is complex. On the basis of summing up the law of the evolution of the channel, combined with the construction effect of the first stage of the project. Comprehensive analysis of the characteristics of the recent changes of the channel and forecast of the evolution trend of the waterway. The analysis shows that after the implementation of the first phase of the project, the right boundary of the entrance of the mouth water channel of the lotus root pool and the channel of the transition section have been basically controlled. The pattern of beach and channel is stable in the near future, so we should seize the present favorable opportunity to carry out the follow-up project, consolidate the effect of the existing project, and further improve the waterway condition.
