本文介绍了等截面多风口送风管道内静压分布基本式理论推导和风口等量率计算方法,着重对工程实践中应用较多的大阻力管道和小阻力管道压力分布特性进行分析比较,并根据实际地下工程测定数据验证其理论计算可靠性,可供道路隧道等量送风长管道和轨交地下车站站厅站台公共区、设备管理用房等量送风管道设计计算和工程调试作借鉴和参考。
This paper introduces the basic theory derivation of the static pressure distribution in the cross-section multi-tuyere air supply duct and the calculation method of the air volume equivalent rate. Emphatically analyzes and compares the pressure distribution characteristics of the large resistance pipe and the small resistance pipe with more applications in engineering practice According to the actual underground engineering data to verify the reliability of theoretical calculations for the same amount of air supply tunnel road long pipe and rail transit stations station hall station public areas, equipment management room, the same amount of air supply pipe design calculations and engineering debugging for reference And reference.
