石浦港航道工程潮流泥沙数值模拟

Tidal current and sediment numerical simulation of channel project in Shipu harbor

分析工程海区自然条件,建立基于不规则三角形网格考虑波浪作用的潮流泥沙数学模型。在对模型进行充分验证的基础上,研究各航道方案影响下的潮流泥沙运动规律,并分析大范围海域潮流特征、进港航道口门位置流态特征、航道内横流、对周围港区影响、对潮位影响和对石浦港5个口门分流比的影响等,预测各方案泥沙回淤与莫拉克台风过程下的骤淤情况。

The hydrology and sediment environments in the ocean area near the project are analysed firstly. Then,a two-dimensional model of wave,tidal current and sediment transport is seted up and fully verificated to study the tidal and sediment transport law after the channel project,which analyses the tidal current characteristics,entrance flow state,cross flow in channel,influnce of area aroud,tidal level change and diversion ratio of the five waterway entrance.
