摘　　要：在大连湾海底隧道工程中首次应用了透水式接岸结构,采用数值模拟的方法计算了大连湾海底隧道接岸结构施工后的流场和水体交换,并与传统的不透水方案计算结果进行了对比分析。研究结果表明:透水式接岸结构方案中水流会产生明显的横跨隧道方向的流动,对隧道两侧的水体交换有改善的作用,更能促进周边水体交换。这种透水结构具有推广应用价值。Permeable type shore connection structure was first applied in the Dalian Bay Subsea Tunnel Project.Numerical simulation method is used to calculate the flow field and water exchange after the construction of the shore connection structure of Dalian Bay subsea tunnel,and the results were compared with the traditional impermeable type.The research results show that the water flow in the permeable type shore connection structure will produce obvious flow across the direction of the tunnel,which can improve the water exchange on both sides of the tunnel and promote the exchange of surrounding water.The permeable type structure has the value of promotion and application.
