Abstract—In order to solve the hypoxia problem in Qinghai-Tibet the frozen tundra; the physical demands on the workers were
railway tunnel construction, on the Qinghai-Tibet Pleatu, a enormous [3]. How to improve the hypoxic condition in
pressure swing adsorption (PSA) cycle to concentrate oxygen humans is one of the most difficult problems, especially for
from the low pressure atmosphere at high altitude had been tunnels development. Most tunnels of the Qinghai-Tibet
developed. Two PSA oxygen generation stations were constructed railway engineering lie in the areas over altitudes of 4000 m
which located in Fenghuoshan about 5000m high above sea level. and the lower oxygen concentration from air es the key
Furthermore, a system of disperse oxygen supply in tunnel to develop tunnels[
