| Abstract: | In order to analyze the characteristics of tunnel ventilation system with unidirectional longi-tudinal slope and to meet the health standards of its normal driving environment issues and smoke ex-hausting in case of fire,the analysis of air demands and economic comprehensive comparative of sever-al schemes is performed.Finally,a blow and exhaust ventilation model with one inclined shaft is used to solve the problem of air demands unbalance between the uphill and downhill tunnel and fire smoke control. |
