摘　　要：风灾调查表明,加油站的破坏大多始于围护结构的破坏。采用Auto CAD结合GAMBIT进行了加油站的几何建模,在GAMBIT中进行了结构域和流体域的网格划分,建立了计算模型。探究了与加油站一定距离的工作室对矩形加油站风荷载特性的影响,给出了不同距离下的风载体型系数。According to the survey,the damage of gas station is mainly caused by the damage of the enclosure structure.In this paper,AutoCAD and GAMBIT were used to carry out the geometric modeling of the gas station.Then,the fluid domain and structure domain were meshed in software GAMBIT to establish the calculation model.At the same time,the influence of the studio on the wind load characteristics of rectangular gas stations was studied.

关 键 词：风荷载 数值模拟 加油站 罩棚 风压系数
