摘　　要：建立了徒骇河二维潮流数学模型,模型采用数学物理方法,将不规则域下求解变换成矩形规则域下求解,计算中,首先采用天然实测资料对模型进行率定,通过有关参数调整,使数值计算成果与天然实测资料达到精度要求。然后通过对自然状态下潮流过程的模拟,分析河段通航条件以及潮位、潮流特征。随后对航道不同疏浚方案和取水条件与潮流的相互影响进行计算,研究航道不同疏浚方案引起的潮流变化。最后采用分析方法,对航道不同扩建方案的回淤以及取水口最大取水能力进行预测。Two - dimmension tidal mathematical model of Tuhaihe river was established. The model was verified with the nature data, and the calculated result of model was consistent with the nature data by adjusting some parameters. Then navigation condition and the tidal flow characteristic was analyzed based on the simulation of tidal water level and tidal current in nature. Furthermore, the mutual reaction of different channel dredged plans, water took out and tidal flow were simulated and analyzed. Finally, distribution of sedimental deposition thickness along waterway and capacity of water took out upstream were doped out.
