摘要
以马家咀水道航道整治一期工程为例,根据支汊控制工程实施前后的实测资料,分析支汊发展的动力条件,从工程与水沙动力条件适应性的角度,对控制工程的效果进行研究,指出工程存在的不足,给出实施后续完善措施的原因,在此基础上,总结汊道治理的经验与认识。
The development of branch channel will certainly destabilize the navigation condition in main channel. Hence the restrictive measures on developing branch channels are carried out in recent waterway regulation projects. This paper carries out a comparison study on flow and sediment transport characteristics based on the before and after project observed data in Majiazui channel. The flow dynamic conditions of branch channel development and the effect of the controlling projects are also analyzed from the standing point of the adaptation of river dynamic. Moreover, the deficiency of the Majiazui waterway regulation project and the improvement measures are also presented. The cognitions of branch channel waterway regulation are also summarized based on above analyses.
