PRESSURE WAVE REDUCING CONSTRUCTION IN TUNNEL AND PRESSURE WAVE REDUCING METHOD IN TUNNEL

摘要

PROBLEM TO BE SOLVED: To provide a pressure wave reducing construction in tunnel and a pressure wave reducing method in tunnel capable of reducing a micropressure wave and rush wave at the mouth of tunnel or the like during the rushing of a train.;SOLUTION: At a lateral cross section vertical to a tunnel center line 81a extending in parallel to the extending direction of a double truck type tunnel 81 where the overall cross section in the extending direction of a micropressure wave reducing structure 10 or the like, the location of the center line 10c of the micropressure wave reducing structure 10 is aligned with a horizontal projected position of the center line 84a of a running train 84 which is rushing in.;COPYRIGHT: (C)2002,JPO
