연속터널에서 터널출구 미기압파를 저감할 수 있는 스노우 쉘터 개발에 대한 연구

초록

There are many tunnels located apart short distance from each other in mountainous country like Korea. Serial tunnels are connected by snow at the shelter in many cases. This study presents some countermeasures against micro-pressure wave at the tunnel exit using snow shelter. Througn 1/60 scale model laboratory test, we find that snoe shelter with 3.6m slit and slit cover show the effect of reducing the micro pressure wave to about 50.6%.
