スリット付きシェルター内圧力変動に関する模型実験

抄録

In the Shinkansen lines, snow shelters with slits linking neighboring tunnels are frequently built for snow disaster prevention. Furthermore, these shelters can act as countermeasures against micro-pressure waves by installing horizontal slits on their walls. However, the longitudinal pressure distribution inside the shelters remains unknown. Therefore, it is important to understand how to further accelerate the Shinkansen. In this study, a model experiment was conducted on pressure variations in a shelter with a slit. The experimental results clarified the characteristics of pressure distribution in the shelter.
