A study on the carbonation of the lining of vehicular tunnel based on ventilation system

This study was performed to analyze the carbonation of the tunnel linings concentrating on the 7 public service-in road tunnels in Korea and to commpare the trend of carbonation as to ventilation systems. The progress of carbonation in study was more conspicuous at the end of tunnels than the beginning of it. Likewise, it was remarkable in the tunnels of semi-transverse ventilation and transverse ventilation system rather than natural ventilation system, because traffic and other contaminants are more in such ventilation systems.
