| 摘 要： | 为了研究跨海大桥桥墩对周围海区的潮位、水流、潮量等水动力环境的影响,文中以浙江省温州市大门大桥为例,建立了二维潮流数学模型,进行相关计算分析。研究表明,桥墩建设后增加了桥位水域的阻力并减小了过水断面,从而对周围海区的水动力环境产生一定影响,但影响范围仅限于局部。

| Abstract: | To study the effect of the pier upon the hydrodynamic conditions of water level,flow velocity and tide flow in the sea area where the bridge are built to connect the land and island,taking Dam-men bridge as an example,a two dimensional hydrodynamic numerical model was developed.The results show that the drag force on flow is increased and the flow section area is decreased by the pier built in the sea.And then the impact upon the hydrodynamic conditions will be produced,but it is only limited to the surrounding sea area. |
