Primary Study of Ventilation Schemes for Xiangjiang Tunnel on Changsha Nanhu Road

On the basis of status quo and tendency of China national economic and technological development and by reference to the associated design theories and rules of highway tunnel ventilation as well as experiences of the constructed similar projects at home, this paper probes and discusses the factors affecting establishment of ventilation schemes for the tunnel in allusion to engineering features of Xiangjiang Tunnel on Changsha Nanhu Road, and proposes a ventilation scheme that not only satisfies driving security inside the tunnel and the requirements of outside environmental protection, but also is favorable to reduce project cost and decrease operating costs.
