극한지 외기온도 변화에 따른 철도터널 동결깊이 특성에 관한 연구(북한지역을 중심으로)

초록

Railway construction of the domestic was built on the hub of Gyeongbu and Honam Line. Currently, Wonju-Gangneung high-speed railway is under construction. Railway construction of mountainous areas of Kangwon is also being pursued such as Chuncheon-Sokcho railway line construction feasibility study. While, The temperature condition in southern part of Korea is not severely considered. However, In consideration of the railway construction of North Korea, it is necessary to consider the impact on the climate diversified. The temperature range which is freezing to hot through a year in North Korea is investigated. The extreme outside temperature simulation analysis of the railway tunnel freezing depth distribution characteristics of climate change in North Korea is expected. Railway tunnel considering the extreme freezing temperature condition was studied in freeze depth analysis using the characteristics of measured road tunnel data.
