In this paper we deal with the study regarding numerical study of pressure wave in underground station with vent shaft position. When the high-speed train passes the underground station, it generates a large pressure wave, which causes the vibration with noise, according to the piston effect. It makes the noise problem with ear discomfortable of the passengers at the high-speed railway underground station. This work is presented the numerical analyzing of the pressure wave"s magnitude and tendency by the position of vent shaft in construction and environmental dimensions. We were installed the vent shaft in and out the underground station to reduce the pressure wave. We analyzed pressure field in the underground station by using axis two-dimensional simulation. We determined the boundary and CFD operating conditions by comparing the experimental data, which were submitted to Hong Kong university by Kwun hing, Wu, to verify the reliability. And we derived the results that we had been changing the position of vent shaft based on the model of the underground station and the tunnel from A line Daegok station of underground GTX. From the result, we can have a conclusion that the role of vent shaft respectively was different according to the position. Vent shaft in underground station reduced wide pressure field. And vent shaft out underground station reduced initial pressure peak value.
