| 摘 要： | 对马汊河分洪道扩挖工程前后的水流流态进行数值模拟,并选取2010年和2015年的实测流量、流速和水位等资料对模型进行验证,研究马汊河扩挖工程对河道水流流态的影响。结果表明,扩挖工程实施后河道水位较工程前有所降低,中游段雍水情况得以解决,河道流速、流量和过流能力都增大,有效提高了河道的泄洪能力。研究结果对马汊河以及滁河的防洪具有重要的理论及现实意义,也可为其他河道的扩挖工程提供重要的借鉴。

| Abstract: | The flow regime of the Macha River before and after the project was simulated with numerical model, and the model was calibrated with the data of observed discharge, velocity and water level. The results show that the flow capacity is increased and the water level is lower after the project construction, which can meet the requirement of the regulations. The research results have important reference value for other river diversion project. |
