摘要
采用刚性模型测压风洞试验与CFD数值模拟相结合的方法，对大型客运码头风荷载特性和风环境进行了分析。结果表明，CFD数值模拟得到的码头屋盖风荷载分布与试验结果相吻合，能够用于模拟复杂建筑群的绕流；客运码头建筑物的布置形式对其屋盖风荷载影响较大，降低屋盖下方附属建筑物的高度，可以有效缓解气流在屋盖前缘的分离，减小作用于其上的风荷载。码头风环境分析结果表明，建筑物对气流的干扰作用是引起风加速的主要原因，算例客运码头的风环境问题较为突出。
Abstract
Wind tunnel test using rigid model and CFD numerical simulation has been carried out to investigate the wind load distribution and the wind environment of large ferry terminal. Wind load distributions on the roof of the ferry terminal drawn from numerical simulation agree with the results drawn from wind tunnel test, which shows that the provided numerical model can simulate the airflow around the ferry terminal. Analysis results show that, the layout of buildings in the ferry terminal affects the wind load on the roof. With decreasing of the height of the ancillary buildings under the roof, the separation of airflow at the edge of the roof is relieved and wind load acted on the roof is decreased. Analysis about the wind environment shows that, the interference effect caused by the buildings is the main reason for wind speed acceleration, and the problem of wind environment around the ferry terminal is prominent.
