摘要
应用多功能航标的实测数据建立平面二维水流数学模型,准确复原所在河道流态,分析了模型的可适用性及可调整性,结果表明:1)模型适用性较强,在初始条件、边界条件匹配和不匹配时,模型均可应用多功能航标实测数据实现对河道的流态复原,其中水位误差在10 cm以下,流速误差约0.2 m s,流场复原与实际情况相符。2)模型具有较好的参数可调整性,不同情况下依据多功能航标数据通过局部参数微调即可完成模型的率定。
The plane two-dimensional flow mathematical model is established by using the measured data of the multifunctional navigation mark,and the flow state of the river where it is located is accurately restored.The applicability and adjustability of the model are analyzed.The results showed that:1)The model has strong applicability.When the initial conditions and boundary conditions match or do not match,the model can use the measured data of multifunctional navigation mark to restore the flow state of the river.The water level error is below 10 cm,and the flow velocity error is about 0.2 m s.The flow field restoration is also consistent with the actual situation.2)The model has good parameter adjustability.Under different circumstances,the model can be calibrated by fine-tuning local parameters according to the multifunctional navigation mark data.
