A study on the Applied Technology of a Case for Underground Structures Considering Downtown Site Conditions

도심지 여건을 고려한 지하구조물 공사사례의 시공기술요소에 관한 연구

Underground structure construction in the downtown is very difficult despite the development of construction technology. We have been a lot of research in order to solve the problem, it was a remarkable achievement. But there are still many difficulties. This study is to analyze the construction technology to demolish the existing underground structures and to build new building applied topdown method at the same time. This technology was effective to suppress interference between the exsisting structure and new building. Therefore, this technology is expected to be able to be used in similar cases in the future.
