Mike 21在梁济运河长沟船闸防洪影响评价中的应用研究
|
摘要
目前,计算水动力学一维、二维模型的研究比较成熟,三维模型由于需要精细的定解和参数识别条件而应用较少。在浅水河流、湖泊数值模拟的实践中一维模型过于简单,二维模型则得到了非常广泛的应用。如太湖风生湖流的数值模拟、巢湖流场的数值模拟、珠江口伶仃洋的流场模拟、洪泽湖混合流数值模拟以及三峡库区岸边污染混合区数值模拟与分析等都采用了二维模型。
对于河道内建筑物对河道防洪流态影响的模拟分析,一维模型计算难度较大,且成果精确度较低,三维模型虽然精确度较高,但是模型搭建计算难度较大,一般工程应用较少,故现在国内外在河道局部流态模拟分析中,二维模型应用较多且结果能够满足评价分析要求,故在河道、河口、海湾的水动力模拟分析中应用广泛。
本研究结合梁济运河上拟建的长沟船闸工程,采用丹麦水力研究所(DanishHydraulic Institute,简称DHI)开发的MIKE 21中的水动力模块(HydrodymamicModule),根据工程相关资料,确定模拟计算的边界条件,创建模型对长沟船闸项目闸址处河道设计洪水工况下流态进行动态的模拟,对计算结果进行后处理,提取所需数据成果、图表,并对计算成果进行分析,得出分析结论;对拟建船闸对梁济运河防洪影响进行客观的评价,针对工程设计提出相应的防治措施及建议,为河道管理部门对河道的防洪管理提供依据。
通过本项目的研究也为今后内河河道内建设项目的防洪影响评价提供有参考价值的理论、方法。
One-dimensional and two-dimensional hydrodynamic model are compared mature at present. But three-dimensional hydrodynamic model is rarely used for the requirement of fine solution and parameter-identify condition. One-dimensional hydrodynamic model is too simple for simulation of shallow stream and lake and two-dimensional hydrodynamic model is used extensively. For example, the simulation of wind driven lake current of Tai lake, the numerical simulation of Chao lake flow, the flow simulation of Lingding ocean at Jujiang river estuary, the mixed flow numerical simulation of Hongze lake and the flow simulation at the bank area of three gorges are all studied by two-dimensional hydrodynamic model.
The simulation analyses for the impact of channel building on flood protection are difficult using One-dimensional hydrodynamic model and the ratio of precision is low. And the precision is better for three dimensional hydrodynamic simulation but the building of the model is difficult. So the two dimensional hydrodynamic model is used extensively in simulation of stream local flow and the result is satisfied and two dimensional hydrodynamic model is used extensively for stream, estuary and bay flow.
In this study, Hydrodynamic Module of Danish Hydraulic Institute- MIKE 21 is used for long ditch lock project at Liangji canal which will be constructed. The boundary conditions are defined according to the relative material. The channel flow of design flood situation at lock site is simulated by MIKE 21. The result data, figures and tables are extracted and the conclusions are given through the analyses of results. The impact of lock on flood protection at Liangji canal is analyzed. The control methods and suggestions are given. The study supplies base rule condition for administration of flood control.
The study also can be used for flood protection impact of other channel projects and the theory and methods are valuable for other similar studies.
