公路隧道纵向通风分析与计算

Analysis and Calculation of the Longitudinal Ventilation in the Road Tunnel

本文分析了公路隧道在纵向通风情况下的有害气体浓度分布规律、所需最小风量和最大可能长度，并给出了一个工程计算实例．

In this paper, analysises are made of the distribution regularity of harmful gases density of concentration the minimum quantity of the fresh air needed and the possible condition of maximum length of the road tunnel under the longitudinal ventilation. A calculated example of the real engineering is also given.
