本文通过高背洲滩整治情况介绍,着重谈谈水流动力轴线与河床变形的相互关系,从客观现象所反应的事实出发,从理论上探讨河床变形的某些基本规律。同时认为河床变形的主要原因是由于水流动力轴线的变化,对整治方案的确定,只要“定性分析准确、定量分析合理、逻辑推导客观”,整治工程也是有一定把握的。 Based on the introduction of Gaoqiuzhou Beach remediation, this paper focuses on the relationship between the axis of water flow and the deformation of riverbed. Based on the fact that the objective phenomenon reacts, some basic laws of riverbed deformation are theoretically discussed. At the same time, it is considered that the main reason of the riverbed deformation is the determination of remediation plan due to the change of water flow axis. As long as “the qualitative analysis is accurate, the quantitative analysis is reasonable and the logic is objective,” the remediation project is also certain.
