Abstract

Since the domestic utility tunnels were built mainly in the development project of the new city, they are all in the form of cut-and-cover box tunnel. But, in the case of overseas construction of utility tunnels for existing urban areas, the bored tunnel types are mainly adopted. It is reasonable to install bored tunnels in a downtown area because it is difficult to block the roads or install bypass roads due to heavy traffic and civil complaints. In order to activate the utility tunnels in bored type, it is necessary to secure optimized cross-sectional design technology considering the optimal supplying capacity and mutual influencing factors (Thermal Interference, electrolytic corrosion, efficiency of the maintenance, etc.) of utilities (power cables, telecommunication cables, water pipes, etc.). The optimal cross-section design method for bored utility tunnels is ultimately to derive the optimal arrangement technique for the utilities. In order to develop the design methods, firstly, the cases of tunnel cross-section (Shield TBM, Conventional Tunneling) in overseas shall be investigated to analyze the characteristics of the installation of utilities in the section and installation of auxiliary facilities, It is necessary to sort out and analyze the criteria related to the inner cross-section design (arrangement) presented in the standards and guidelines.

국내 공동구는 주로 신도시 개발사업에 포함되어 건설되었기 때문에 모두 개착 BOX 형태를 이루고 있으나 기존 시가지를 대상으로 독자적 공동구를 건설 중인 해외의 경우 터널식 공동구 형태를 주로 채택하고 있다. 공동구의 사회적 요구가 큰 중심가 도심지는 교통량이 많아 장기적으로 차로를 차단하거나 우회 차로 설치가 곤란한 것이 일반적이므로 터널식 공동구 설치가 합리적이라 하겠다. 이러한 터널식 공동구 활성화를 위해 공동구 최적 설계용량 및 수용시설(전력, 통신, 상수도 등)별 상호 영향인자(열간섭 및 전식, 유지관리 효율성 등)를 고려한 최적화된 단면설계 기술력을 확보할 필요가 있다. 터널식 공동구의 최적단면 설계기술이란 결국 공동구내 수용시설의 최적 배치기법을 도출하는 것이라 할 수 있다. 이러한 설계기법 도출을 위해 우선적으로 해외의 터널식 공동구(Shield TBM, Conventional Tunneling) 내공단면 적용사례를 조사하여, 단면 내 수용시설의 배치현황, 부대시설 설치 등의 특징을 분석하고, 또한 국내 ․ 외의 공동구 설계기준 및 지침서에서 제시하고 있는 내공단면 설계(배치)와 관련한 기준사항들을 정리 ․ 분석할 필요가 있다.
