摘要
利用水深平均的二维水动力数值模型对深圳西部填海工程引起的出海河流泄洪能力影响进行了研究。控制方程离散时采用三角形和四边形混合单元。采用实测资料对数值模型进行了验证。计算结果与实测数据吻合良好。利用验证后的模型,对不同工况进行了预测。根据计算结果,提出了确保河流泄洪能力的措施。该模型可直接用于深圳地区的相关问题的研究。
Influences from the reclamation projects in western part of Shenzhen Bay on the discharging capacities of the rivers flowing into the sea are studied herein with depth-averaged 2D hydrodynamic numerical model. The governing equations are discretized by a hybrid grid system comprising rectangular and triangular ceils. The simulation model is validated by the measured data. The calculated results coincide with the measurements satisfactorily. The predictions for different cases are made by the validated model, and then some suggestions are presented on the basis of the predicted results. The simulation can be used for similar researches concerned.
