摘　　要：文章从公路隧道纵向通风计算特点分析入手,根据流体的连续性原理对单竖井送排式通风计算公式进行了扩展,提出了多竖井送排式通风计算方法,利用这种方法能够求出多竖井送排式通风中各段隧道最经济的设计风量,通过编程并实施,证明其具有很大的实用价值。From the analysis of the characteristics of longitudinal ventilation computation for a road tunnel, computing equations and algorithm for multi - shaft blow - in and exhaust ventilation systems are presented in the paper. The algorithm is extended from the computation formulae for one - shaft blow - in and exhaust ventilation system according to the axiom of fluid continuity. The most economic designed air volumes on all tunnel sections in a multi - shaft blow - in and exhaust ventilation system can be found out through the method which is of great value for application.
