| 摘 要： | 首次提出了采用充水式橡胶坝导流堤对码头后方进行清淤减载的工程方案，并结合实际工程构建了码头后方三维流场数学模型，研究了垂直导流堤、下挑式导流堤、上挑式导流堤、离岸短堤、正八字型导流堤和倒八字型导流堤6种不同拓扑构型的橡胶坝导流堤对码头后方流场的影响，探讨了码头后方瞬时涡量、三维流线拓扑、时均流速及雷诺应力分布随不同型式导流堤的变化规律。研究结果表明，当布置橡胶坝导流堤后，码头后方流场流速会明显增大，其中垂直导流堤和上挑式导流堤挑流效果最为显著。

| Abstract: | This paper first proposes a concept of the rubber dam diversion dike filled with water to solve the sediment deposition behind the pile-supported wharf. Three-dimensional numerical simulations are performed on flow past the rubber dam diversion dikes in six different configurations, such as the vertical diversion dike, up-warping diversion dike, down-warping diversion dike, short diversion dike, forward and reversed eight diversion dikes. The instantaneous vorticity contours, streamline topologies, distributions of the mean flow velocity and Reynolds stress behind the pile-supported wharf are analyzed. The results show that when the rubber dam diversion dikes are arranged behind the wharf, the flow velocity increases significantly. The vertical diversion dike and up-warping diversion dike have the most significant effects on the flow field behind the wharf. |
