More Information
Summary:The invention provides a jet fan operating distance calculation method for improving the ventilation performance of a tunnel, which comprises the following steps of: enabling a tunnel entrance pressure coefficient to be equivalent to the sum of all local pressure coefficients of each construction section of the tunnel, and establishing a corresponding minimum total rise pressure calculation formula by combining a tunnel construction wind speed design index; the tunnel jet fan operating distance calculation algorithm accords with engineering practice, reasonably applies equivalent thoughts, and provides powerful technical support for improving tunnel ventilation. 本发明提供了一种旨在提高隧道通风性的射流风机作用距离计算方法，将隧道入口压力系数等效为隧道各施工段所有局部压力系数之和，结合隧道施工风速设计指标，建立对应最小总升压力计算式，最终推算出隧道射流风机作用距离公式，该算法符合工程实际，合理运用等效思想，为改善隧道通风性提供了有力技术支持。
