摘　　要：多功能大气边界层风洞是风工程研究必不可少的设备。以石家庄铁道大学风洞为基础,介绍了多功能大气边界层风洞设计的技术要求,对风洞的气动设计、附属设备设计、结构设计、建设方式、流场校测结果和风洞的特点进行了详细的说明。流场校测结果和运行后的基础研究和应用研究试验表明:流场指标高、使用方便,满足例如风雨、风雪等特殊试验要求,风洞的气动设计、结构设计是成功的,可为今后类似风洞的设计和建设提供参考。Mulitifunction boundary-layer wind tunnel is a necessary facility for wind engineering research. Based on the wind tunnel of Shijiazhuang Tiedao University, the technical requirement of this wind tunnel was introduced. Especially the aerodynamic design, accessory facilities design, structure design, construction mode, results of flow field measurement, and characteristics of the wind tunnel are explaned in detail. The measurement results of tunnel flow field show that the flow field is good. Basic research tests and applicational tests show that the wind tunnel is easy to operation and it meets the demand of special function such as rain-wind test, snow-wind test. All these prove that the aerodynamic and structure design are successful. This wind tunnel example provides a reference for the design and construction of similar wind tunnels.
