Abstract

Population of urban areas is rapidly increased due to urbanization. This situation leads to lack of surface space. So, underground space has been developed for resolving the problem of congested urban areas. Many studies have researched for this situation. However, previous studies mainly focused on behaviour of structures. Researches about behaviour of soil are lacked. For this reason, this study has investigated interactive behaviour between embedded pile and its surrounding ground due to tunnelling. Soil deformation is observed by the close range photogrammetric method and image processing in the model test. These data are compared with numerical analysis.

도심지 인구는 빠르게 증가하고 있으며, 지상공간은 점차 부족해지고 있다. 이러한 현상에 대한 대책으로 지하공간 개발이 지속적으로 이루어져왔으며, 지하공간에 대한 연구도 더불어 증가하고 있다. 하지만 터널굴착과 같은 지하공간에 대한 연구는 터널 굴착방법, 터널 및 상부구조물의 형상, 주변지반의 조건에 따라 다양한 결과를 가져오며, 기존 지하공간에 대한 연구는 수치해석으로 터널굴착과 주변 구조물의 상관관계를 예측하거나 실내모형시험을 통해 구조물의 거동 및 지표침하를 관측하는 정도에 초점을 맞춰 연구가 진행된 것이 많은 비중을 차지하고 있는 실정이다. 따라서 본 연구는 지반 주변 구조물뿐만 아니라 지반의 거동 및 구조물과의 상호관계를 실내모형시험을 통해 모사하였다. 또한 터널굴착에 따라 변화하는 지반의 거동을 근거리사진계측 및 이미지프로세싱 기법을 통해 관측하고, 유한요소 수치해석을 이용한 역해석을 통해 다양한 지반의 상태를 예측해보았다.
