Abstract

Although the TBM method is mainly adopted in overseas market including the Europe, etc, the method scarcely adopted in domestic market. For highly enhancing applications of the TBM method for railway, it is needed to select the optimal cross-section considering design elements of civil engineering and aerodynamic effects. In addition, it is needed to establish a plan of proper section as well as reviewing aerodynamic effects and consideration about civil engineering elements such as length of tunnel, speed of railway, height of whole lines and size of utility tunnel, etc. Even though it should be recently considered high-speed railway tunnels and required to be standard establishments in aerodynamic reviews, it is being applied to be criteria of inconsistent pneumatic analysis owing to be not related with domestic standards. In this study, therefore, we are willing to establishment of domestic and foreign aerodynamic standards and investigate correlation between an optimal cross-section and aerodynamic effects of TBM railway tunnels.

유럽 등 해외에서는 TBM 굴착방식을 이용한 터널이 다수 건설되고 있지만, 국내에서는 거의 적용되고 있지 않다. TBM 철도터널의 적용성을 높이기 위해서는 토목적 설계요소와 공기역학적 영향을 고려한 최적단면을 선정할 필요가 있다. 이러한 최적단면의 선정시에는 터널 연장, 열차 속도, 전차선 높이, 공동규 규격 등 토목적인 설계요소에 대한 고려와 함께 공기역학적 영향을 검토하여 적정 단면 계획의 수립이 필요하다. 공기역학적 검토시에는 최근 철도터널의 고속화를 고려하고 적절한 분석기준의 수립이 필요하지만 현재 국내에서는 관련기준이 없어 터널마다 상이한 공기압 분석기준이 적용되고 있는 실정이다. 따라서 본 연구에서는 국내외 이명감 및 미기압 분석기준에 대하여 검토하고, TBM 터널단면별 공기역학적 분석을 통해서 TBM 철도터널의 단면선정시 공기역학적 영향과의 상관관계에 대해 분석하였다.
