摘要
根据感潮河网的水力特性,采用有限差分格式求解圣维南方程,建立了三洋港水动力数学模型,并利用2010年实测资料对模型进行验证。根据施工截流的要求,利用水动力模型对龙口进行模拟计算,从而确定中泓截流方案所需要的关键数据。据此制定截流方案,成功实现截流。本文对此加以介绍。
Finite difference scheme is adopted for solving Saint-Venant equation according to hydraulic characteristics of tidal river network.Sanyang Port hydrodynamic mathematical model is established.Measured data in 2010 is utilized for validating the model.Hydrodynamic model is utilized to simulate and calculate closure gap according to construction closure requirements,thereby determining key data required by midstream closure plan.Closure plan is developed accordingly,thereby successfully realizing closure.The condition is introduced in the paper.
