초록

도심지 교통해소를 위한 수단으로 터널구조물의 건설은 날로 증가되는 추세에 있다. 그러나, 새로운 터널구조물이 기존 터널구조물과 인접 또는 교차하여 건설됨에 따른 기존 터널구조물의 운영상의 안정성 확보는 상당히 중요하다. 이에 따라, 이 논문은 기존터널과 인접하여 건설되는 신설터널과의 상호거동에 대한 연구로써, 특히 상하교차터널에 대하여 중점을 두었다. 이 연구는 1g 모형시험을 실시하고 그들 결과의 분석을 통하여 교차터널의 거동에 대한 연구 고찰하였다. 또한 교차터널의 설계방향 제시함으로써 보다 실질적인 교차터널의 설계기술 발전을 위하여 활용되어 질 것으로 판단된다.

This paper describes a study of the effect of shield tunnel construction on the liners of nearby existing perpendicular tunnels. The research programme investigated the influence of tunnel proximity and alignment, liner stiffness on the nature of the interactions between closely spaced tunnels in clay. A total of two sets of carefully controlled 1g physical model tests, including the same test for repeatability, were performed. A cylindrical test tank was developed and used to produce clay samples of Speswhite kaolin. In each of the tests, three model tunnels were installed in order to conduct two interaction experiments in one clay sample. The tunnel liners were installed using a model tunnelling machine that was designed and developed to simulate the construction of a full scale shield tunnel. The first tunnel liner was instrumented to investigate its behaviour due to the installation of each of the new tunnels. The interaction mechanisms observed from the physical model tests are discussed and interpreted.
