摘　　要：针对防风抑尘网结构设计的参数取值问题,以已建防风抑尘网工程为实例,采用风洞试验与规范规定相结合的方式,论述了散货堆场防风抑尘网的结构设计方法,集中分析了风荷载体形系数、风振系数等的取值方法。结果表明:防风抑尘网作为港口工程散货(煤炭、矿石)堆场的重要防风抑尘措施,具有受力明确、荷载传递路径清晰、施工便捷等特点。以《建筑结构荷载规范》的风荷载计算公式为基础,合理选取风振系数、体型系数等设计参数,能够保证结构的安全、稳定、经济、合理。In this paper, the existing wind and dust suppression net projects are taken as an example to address the value problem of parameters in the structural design of wind and dust suppression nets. Specifically, by combining wind tunnel tests and specifications, the structural design method of wind and dust suppression nets in bulk cargo yards is discussed, and then we focus on analyzing the method of determining the values of parameters such as the structural shape factor of wind loads and the wind vibration coefficient. The results reveal that the wind and dust suppression nets, as an important wind and dust suppression measure for bulk cargo(coal and ore)yards in port engineering, are characterized by clear force, clear load transfer paths, and convenient construction. On the basis of the wind load calculation formula in Load Code for the Design of Building Structures,reasonable selection of design parameters such as the wind vibration coefficient and structural shape factor can ensure the safety, stability, economy, and reasonableness of structure.
