| 摘 要： | 针对我国东南沿海地区多风的气候特征,采用风洞试验,研究了单栋拱棚和连栋温室的风压分布特点,根据试验结果对常用葡萄栽培设施进行了设计。结果表明:风荷载对单栋拱棚以向上升力为主,风向角为0°时风压变化范围最大。风向角的改变对互插式连栋温室4区和5区影响不大,拱1、拱2的迎风面和拱3的背风面风压是最不利于风压分布的区域。为提高设施的抗风载能力,将拱1的支撑杆换成粗截面杆件,在3区和6区加设支撑杆件;为了降低设施的建造成本,将互插杆件改为水泥支柱。改造后的葡萄栽培设施的抗风能力得到了显著的提高且其建造成本较改造前低。

| Abstract: | Aiming at windy climate in south-east littoral of China,the characteristics of wind pressure distribution in single-tunnel greenhouse and mutual multi-span greenhouse were studied through wind tunnel test,and the usual grape cultivation establishment was designed according to the experimental results.The results showed that the main action force of wind load on singe-tunnel greenhouse was up,and the changeable scope of wind pressure was maximal when wind direction angle was zero degree.The change of wind di... |
