摘要：根据刚性模型风凋测压试验所得数据，研究了不同的周边干扰条件下柜体表面平均风压系数的变化规律，对比分析了不同柜体间距时干扰效应的变化情况。研究结果表明：干扰煤气柜位于柜体的正前方时，柜体逆风面平均风压系数显著减小；干扰煤气柜位于柜体的正后方时，柜体背风面平均风压系数会增大；两煤气柜相互平行时，柜体背风面平均风压系数会减小；柜体间距会对干扰效应产生影响，干扰效应随着柜体间距的变化而发生变化；在逆风面与侧风面，规范值有较高的安全储备；而在背风面，其安全储备略有不足。

Abstract:In order to study the variation regularity of mean wind pressure coefficients on gasholder with interference and the transformation of different distance of interference effect , pressure measurements were conducted in wind tunnel on a rigid structural model . Results showed that in the case the interferential gasholder was located in the front, the mean wind pressure coefficients of windward side would dramatically decrease: the interferential gasholder was located in the rear, the mean wind pressure coefficients of lee side would increase; two gasholder were parallel to each other, the mean wind pressure coefficients of windward side would decrease; distance had a influence on the interference effect, interference effect varid with changes of distance; the safety reserve of code values was sufficient on windward and crosswind side but slightly insufficient in windward side.
Keywords: gasholder;interference: wind tunnels; mean wind pressure; distance between gasholder
