Paper Title:
Comparison of Micro-Pressure Wave Radiated Out of Tunnel Exit between Slab Track and Ballast Track
  Abstract

Based on the one-dimensional unsteady compressible non-isentropic flow theory, micro-pressure wave radiated out of tunnel exit generated by a high-speed train entering a tunnel was investigated. In calculation process, the track roadbed and tunnel length were considered. The results, which were qualitatively and quantitatively analyzed, show that the ballast track has reduction effect of micro-pressure wave in long tunnel.
