초록

국내 한랭지역(강원권)의 경우 낮은 연평균 기온으로 인해 도로표면이 자주 결빙된다. 특히 터널의 입출구의 도로면은 지형적 영향으로 그늘이 생기기 때문에 타 도로면에 비해 결빙이 많이 발생하게 된다. 이러한 결빙을 방지하기 위해 염수분사장치, 전열선 설치, 지열이용 등이 주로 사용되고 있다. 하지만 이런 방법들은 환경오염, 많은 공사비, 유지보수비 및 정기적인 점검 등의 문제점들이 있다. 본 연구에서는 기존도로의 결빙을 방지하기 위해 발열체인 CNT를 이용하여 콘크리트 슬래브의 발열효과를 살펴보고 최적의 CNT설치 간격을 결정하였다.

In the cold region, road surface is frequently frozen, resulting in property/facility damage as well as people's death. In order to prevent the road surface from being frozen, conventional deicing methods such as salt, geothermal, and electric wires have been widely used. However, theses methods have some problems such as anti-environment, high-construction and -maintenance cost and so on. To improve the drawbacks of aforementioned methods, carbon nanotube (CNT) was used as an heating material in the laboratory test. Through the test, heat transferring effect of CNT on the concrete slab was investigated and maximum interval of CNT installation was determined.
