摘要: 汉江中下游整治工程的实施改变了局部河段的流场形态与水动力因子。本文以汉江中下游典型河段为例，采用平面二维数值模拟方法模拟并研究了丁坝整治工程影响下河道水动力变化情况，定量分析在工程作用影响下的水位和流速变化情况，对进一步研究汉江中下游河道受整治工程等涉水工程影响的水动力因子变化规律和成因机理，为后续汉江中下游保护对策研究提供技术支撑。
Abstract: Since the implementation of the river regulation project in the middle and lower reaches of the Han River, the flow field morphology and hydrodynamic factors in local river sections have changed. This article uses a two-dimensional numerical simulation method to study the hydrodynamic changes in the river channel under the influence of spur dike regulation engineering and quantitatively analyzes the changes in water level and flow velocity under the influence of engineering, and further studies the changes in hydrody-namic factors and causes of water related engineering in the Han River, providing technical support for subsequent research on protection strategies for the middle and lower reaches of the Han River.
