摘要
以计算流体力学（CFD）数值模拟方法对典型体型加油站屋盖表面风荷载进行研究，依据体型系数等对该类屋盖结构风荷载作用规律进行了分析在此基础上对开孔后的屋盖进行研究，研究表明：屋盖上表面主要承受负压，下表面由于挡板的影响，产生不同程度的涡流，导致下表面呈正压负压共存状态，整体呈压力。进一步得出，开孔可以有效地降低风压，但加速了孔洞周围气流的流动，在孔口周边容易形成高负压区。
Abstract
Based on the computational fluid dynamics (CFD)numerical simulation method, the wind load on the roof of typicalgas station roof is studied. The wind load law of the roof structure isanalyzed according to the body shape coefficient. On this basis, theresearch on the roof after opening is carried out. The research shows thatthe upper surface of the roof is mainly subjected to negative pressure,and the lower surface has different degrees of eddy current due to theinfluence of the baffle, resulting in the coexistence of positive pressureand negative pressure on the lower surface. The overall pressure. Itis further concluded that the opening can effectively reduce the windpressure, but accelerates the flow of the air around the hole, and a highnegative pressure region is easily formed around the opening.
