摘要
通过定床模型试验,比较温州七都大桥建桥前后瓯江口水位、流速、流向、汊道分流比等水动力因素的变化,对大桥建成后附近水域流态的变化及防洪、通航条件等的影响进行分析和预测。试验结果表明,大桥建成后对瓯江口的防洪排涝不会产生明显影响,不会改变七都南北汊道的性质,对港区航道影响较小。
Based on the fixed bed model test, we compare the changes of hydrodynamic factors of Oujiang estuary including the water level, flow, flow, branch channel＇s diversion ratio before and after construction of Wenzhou-Qidu bridge, analyze and forecast the variation of flow pattern and near the bridge and the influence on flood control and navigation. The result shows that the construction of the bridge has no significant effect on flood control and drainage of Oujiang and will not change the nature of the seven North-South branch channels, and has little affect on the port channel.
