Abstract：
Based on the construction of the Balangshan tunnel with an altitude of 3 800 m and a length of 8 km, a field test regarding the diffused oxygen supply was carried out for the first time, obtaining variation patterns of subjects' physiological symptoms, such as heart rate and blood oxygen concentration, as well as the oxygen concentration inside the tunnel. It was determined that the diffused oxygen supply, having obvious positive effects on the oxygen concentration and human body function in the tunnel, is a sound method for the construction of tunnels in high-altitude areas, and it is recommended for application in the Balangshan tunnel.
