摘　　要：为了研究横向通风技术在27 m跨度高大平方仓应用可行性,利用仓房安装的横向通风系统和粮堆内部静压测试管,测试了晚籼稻平房仓横向通风系统的流体特性参数,获得了横向通风晚籼稻粮堆的粮层阻力和设施阻力计算公式,试验表明稻谷仓横向通风具有良好的通风均匀性,在适用的单位通风量范围,系统总阻力在1 400 Pa以内,因此横向通风系统应用于27 m跨度的稻谷仓是可行的,为完善横向通风系统设计和应用技术奠定了基础。In order to research the feasibility of the application of transverse ventilation in 27 meters wide paddy warehouse, the fluid characteristic parameters were measured by a set of transverse ventilation system installed in the paddy warehouse and some static pressure tubes in the paddy heap. The calculating formula of unit profile resistance and facilities resistance was acquired. The result indicated that transverse ventilation was of good uniformity, in the applicable range of unit ventilation quantity the total systemic resistance was within 1 400 Pa, which indicated that the scheme of transverse ventilation was feasible to 27 meters wide paddy warehouse, which laid a foundation for improving the design and application of transverse ventilation system technology.
