长大高速公路隧道通风与运行安全分析

对影响隧道安全等级的主要因素进行了分析,从分段纵向通风理论模型中通风动力可控制、阻力可预测、环路单一的特点进行了论述,指出利用分段纵向通风模式可最大程度地解决山岭高速公路隧道正常运行与防火减灾的统一问题。

On analysis of ventilation and operation security of long-large expressway tunnel

The paper analyzes the main factors which affect the security levels of tunnels,illustrates the controllable ventilation dynamics,the predictable resistance and the single loop in the section vertical ventilation theory models,and points out the section vertical ventilation model can maximally solve the problems of regular operation of expressway tunnel and prevention and reduction of fire.
