Feasibility Study on the Road Bridge Passed by Military Heavy Vehicle
Byung-Hee Park, Jae-Ho Song, Il-Young Jang
Abstract
Any vehicle and equipment whose total weight is more than 40ton and its axle weight is 10ton or above is banned to cross any bridge in our country under section 54 in the Highway law. This restriction results from the accumulation and application of safety factors about which there is type specification in the `standard design vehicle`. And in `standard design vehicle`, Vehicle load to bridge is assumed concentrating one. Based on this restriction, there is an issue that military tank which has a total weight of 51ton (63ton in case of the US tank) can not cross any bridge. However, many research and practical examples concerned manifest that it is possible for military tanks to cross these bridges. The reasons of this issue in the current Highway law`s provisions are analyzed in this paper. Correspondingly, feasibility of military tanks passing these bridges are discussed here. At last, considering economical efficiency and practicability for military, several suggestions and improving measures are put forward. This research has certain reality significance to guide bridge design considering the passage of military heavy vehicles.

요지
기존의 SOC를 보다 효율적으로 활용할 수 있는가를 고민하는 것은 SOC의 증설을 위한 연구.개발.투자만큼이나 중요한 문제이다. 또한 총중량 51톤의 군용 중차량인 전차가 현행법상 국내 교량의 통행에 제한을 받고 있다는 현실적인 문제에서 출발하여, 국내 외의 여러 연구 결과를 바탕으로 축하중 10톤, 총중량 40톤의 현 도로법상 차량의 운행제한 조항을 궤도하중인 군용전차에 일괄 적용하기에는 무리가 있다. 미국 및 NATO에서 사용하고 있는 교량해석방법의 또 다른 표준인 표준급수분류제도 등을 이용하여 우리 실정에 맞게 검증하고, 우리의 단위체계나 교량해석방법과는 다른 산물로서의 데이터베이스로 손쉽게 활용할 수 있어야 하겠다.
