Abstract

For the last 60years, North Korea has constructed a lot of roadway bridges with different standard from that used in South Korea, and since North Korea prefer to take advantage of train more than truck for long distance transport, the construction and maintenance of roadway bridges have not been constructed effectively. Upon these situations, an exact evaluation of the resisting capacity for bridges in North Korea has been required to check of any bridge can be used in time of war. This paper introduces an evaluation of bridges in North Korea on the basis of Military Load Classification (MLC). Three different types of concrete bridges are considered, and the numerical analysis and design calculation give the military loadings which can pass through the bridges in North Korea.

지난 60년이 넘는 시간동안 대한민국은 남과 북이 대치한 휴전상태로 각자 다른 기준을 가진 채 기반시설을 발전시켜 왔다. 특히 북한에서는 운송의 주요수단으로 철도를 사용하기 때문에 도로는 잘 발달하지 않았고 그 중에서 도로교량은 세계 기준보다 많이 낮은 수준이다. 이 논문에서는 전시라는 특별한 상황에서 북한교량을 어느 수준으로 판단하고 이용할 수 있느냐에 초점을 두고 북한의 3가지 콘크리트 교량의 표준 도면을 분석하여 군용하중급수 분류법에 따른 군용차량의 북한 콘크리트 교량의 이용 가능수준을 추정하였다. 그리고 상용프로그램을 활용한 유한요소해석을 병행하여 계산 값과 비교하였다.
