摘要
针对三峡工程上游引航道的特点及各种布置方案,采用沿水深平均的平面二维数学模型,分析计算了因船闸充水而在上游引航道中引起的非恒定流运动。成果表明,该数学模型在精确性、收敛速度、稳定性方面有其优越性,为设计部门作方案比较提供了科学依据。
According to the peculiarities of the Three Gorges Project’s lock upper approach channel and various layout schemes, a 2 D mathematical model (averaged in depth) used to analyse and compute the unsteady flow caused by the lock filling is proposed. Calculation results show that the model has the advantages in the aspects of accuracy, convergence and stability. A number of scientific data for selecting feasible scheme are provided.
