摘　　要：依托海拔3 800 m且长8 km的巴朗山隧道工程实例,首次对弥散式供氧进行了现场测试试验,得到了测试人员心率、血氧浓度等生理指标及洞内氧气浓度的变化规律。研究结果表明,弥散式供氧对于提高洞内氧浓度、改善人体机能等方面效果明显,是高原隧道施工掌子面较好的供氧方式。建议巴朗山隧道掌子面采用弥散式供氧方式进行供氧,该研究也为类似高海拔隧道供氧方式的确定提供了设计依据。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.
