摘　　要：以重庆港寸滩码头三期工程的为依托,基于大涡模拟理论,应用有限元软件Fluent模拟高雷诺数条件下的三维流场,得出超临界状态下串联桩上的水流速度和压强,探讨码头结构各排架桩上的阻力系数、水流压强衰减、消能等相关规律,为三峡库区大水位差架空直立式码头在结构设计时考虑水流力的影响提供参考。Based on Chongqing Port Cuntan Terminal Phase 3 Project,Large Eddy Simulation theory and the finite element software＂Fluent＂ are applied to simulate three-dimensional flow field under the conditions of high Reynolds number,educe the water velocity and intensity of pressure on the series piles under supercritical conditions,and discuss the relevant rules of the resistance coefficient,water pressure attenuation and energy dissipation on the wharf bent piles.The above will provide the reference for the water flow effect in the design of the overhead vertical wharf with great water level difference in Three Georges Reservoir.
