基于MIKE11模型的平原感潮河网城市防洪规划研究
|
摘要
平原感潮河网城市人口众多,经济发达,河道湖泊密布。随着近年来城市化的快速发展,城市防洪压力与日俱增。以海门市为研究对象,运用MIKE11模型对研究区域内河网及水工建筑物进行概化,在100年一遇降雨与潮位组合情况下,模拟计算现状和规划工况条件下区域内主干河道的最高水位,对比防洪规划实施前后研究区域内主要河道的水位变化情况,分析防洪规划带来的有利影响。计算结果表明在平原感潮河网城市的防洪规划中,MIKE11模型具有一定的应用价值。在改、扩、新建主干河道和沿江闸站等工程措施下,区域排水能力加大,并阻止长江高潮位的顶托倒灌,河道100年一遇设计水位明显降低。
Plain tidal river networks cities are populous,developing economically and full of rivers and lakes. With the recent rapid development of urbanization. Urban flood control is under increasing pressure. This paper takes the city of Haimen as its research object,adopts MIKE model generalize the river networks and hydraulic structures in the research area,in the hundred years of rainfall and tidal combinations,simulate and calculate the highest water level of the main river in the area under different working conditions,compare The water level change of main rivers in the area before and after the implementation of flood control plan,analysis the beneficial effects of flood control planning. The results indicate that in flood control planning of plain tidal river network city MIKE11 model has a certain value. Under reform,expansion,create new main river channel and lock station and other engineering measures,regional drainage capacity is increased and stop the tide of backwater from Yangtze River,the hundred years design water level of main rivers were significantly lower.
