摘要
为了得到高海拔特长公路隧道施工风机的参数修正系数,利用相似率原理对高海拔地区风机的风压和功率修正系数进行了推导,得到计算公式并用于指导雀儿山隧道的风机选型。结果表明:高海拔隧道与平原地区的风机风量相等;风机风压、功率的海拔高度修正系数公式;雀儿山隧道风机风压的海拔高度修正系数为0.64,并对雀儿山隧道的风机性能曲线进行了修正。
In order to get the parameters of the high altitude of extra long highway tunnel construction fan correction coefficient using similar rate principle of high altitude wind machine pressure and power correction factor is derived,calculation formula and used to guide Queershan tunnel fan selection.The results show that the high altitude tunnel and plain areas fan air flow is equal;fan pressure,the power of the elevation height correction coefficient formula;Queershan tunnel fan pressure altitude correction coefficient of 0.64 and of Queershan tunnel of fan performance curve is modified.
