연속터널에서 터널출구 미기압파를 저감 할 수 있는 스노우 쉘터 개발

The development of snow shelter connecting serial tunnels for reducing the micro-pressure waves.

There are many tunnels located apart short distance from each other in mountainous country like Korea. Serial tunnels are connected by snow shelter in many cases. This study presents some countermeasures against micro pressure wave at tile tunnel exit using snow shelter. Through 1/60 scale model laboratory test. we find that snow shelter with 3.6m slit and slit cover show the effect of reducing the micro pressure wave to about 60.5%.
