Abstract

This study analyzed the causes of frost damage and freezing depth for concrete ballast sites in the Gangwon mountainous area, which has a high freezing index, and considered the equation for freezing depth in concrete roadbeds. Comparing the freezing depth tendencies of concrete roadbeds in the Gangwon mountainous area and Gangwon area, it was found that the freezing depth of concrete roadbeds was higher than that of the Gangwon area when the freezing index was less than 400. However, in sections with a freezing index greater than 400, the freezing depth was higher in the Gangwon area than in the concrete roadbeds. This study proposed an equation for computing the freezing depth in the Gangwon area to provide basic data for establishing preventive measures against frost damage during railway and road construction projects in the Gangwon region.

본 연구에서는 국내 동상피해 발생지역 중 동결지수가 높은 강원산간지역의 콘크리트도상 현장에 대하여 동상피해 원인과 동결심도를 분석하고 동결심도 자료를 바탕으로 콘크리트도상의 동결심도 산정식 및 강원지역의 동결심도 산정식을 고찰하였다. 강원산간지역의 콘크리트도상 동결심도와 강원지역의 동결심도 경향성을 비교한 결과 콘크리트도상은 동결지수 400(℃×일)이하에서는 동결심도가 강원지역의 동결심도보다 높게 나타났으며, 동결지수400(℃×일)이상의 구간에서는 강원지역의 동결심도가 콘크리트도상의 동결심도보다 높게 나타났다. 본 연구를 통해 강원지역의 동결심도 산정식을 제시하여 강원지역의 철도 및 도로 건설사업 시 동상 방지대책 수립에 활용될 수 있도록 기초자료를 제공하였다.
