REDUCTION OF MICRO-PRESSURE WAVE RADIATED FROM TUNNEL EXIT BY SIDE BRANCHES IN TUNNEL

When a train enters a tunnel, a pressure pulse called a micropressure wave is radiated from the other end of the tunnel. Various methods have been applied to the tunnels on the Shinkansen lines to alleviate it. A method using the side branches in a tunnel has been adopted at the Haruna and Nakayama tunnels on the Joetsu Shinkansen. The effect of this countermeasure was confirmed at these tunnels.
