| Abstract: | 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. |
