| Abstract(J) | 高速鉄道の環境問題に，トンネル微気圧波がある。微気圧波対策の一つにトンネル坑口への緩衝工の設置があり，その効果は緩衝工断面積，および側面開口部に依存する。本稿では，微気圧波の現象および新幹線トンネルに設置されている緩衝工の仕様，および緩衝工の性能向上のために実施した模型実験について述べる。 Translation |
| Abstract(E) | Impulsive pressure wave called micro-pressure wave emitted from tunnels is one of environmental problems in high-speed railways. The representative of its countermeasures is a tunnel hood installed at the tunnel portals. The effect of the tunnel hood depends on its cross-sectional area, and the area and the installation position of side openings. This paper expounds the micro-pressure wave phenomena and the specifications of the tunnel hoods installed at Shinkansen tunnels. This paper also describes that the results of model experiments on the effect of the cross-sectional area of the tunnel hood and the optimization method of the side openings of the hood are conducted for speed-up of Shinkansen. |
