| 摘 要： | 采用刚性模型测压试验研究全天候大跨度船库的风荷载分布规律，讨论了高水位、低水位、有船舶停靠、无船
舶停靠4种工况下风压分布特点。结果表明：船库结构内压随风向角变化明显，对结构风荷载影响很大；结构开口造成部分
风向角下结构内表面正压从而增强了结构表面的风吸力；不同干扰状况下结构的风荷载不同，其中低水位无船舶停靠时的
风荷载最大。

| Abstract: | The wind load distribution on all-weather working large-span dock is studied by rigidity model
man metric experiment in the wind tunnel. The effects of high water level, low water level, occupied and unoccupied
on characteristics of wind pressure distribution are discussed. The results show that the effects of internal pressure
on wind load, which is the significant change to the wind direction, is unnegligible; The wind suction is enforced
because of positive internal pressure induced by local openings in some wind directions; The wind loads are different
in interference cases, and the strongest wind load appears in case of unoccupied in the low water level. |
