Abstract
As a part of several Eurasian initiatives, the Korean government is trying to reconnect railways through North Korea to the Asian continent. If South Korea could build a network using railway, it would be a chance to develop a robust economic environment and to motivate economic growth. In the railway reconnection project between North and South Korea, the most important part of the railway roadbed sector is repair or improvement, and then construction of a new line through North Korea. There are not many big differences in the geological conditions; however, climate condition varies greatly during winter. The most significant condition in the safety of railway operation is frost-heaving. However, since South Korea has a relatively mild climate condition compared with North Korea, design and construction specifications under severe weather conditions in winter have not been prepared. This study proposes a plan for revising the railway design standard for underpass structures through an analysis of international standards, leading to site construction to prevent frost-heave.
