프리캐스트 모듈 박스구조 연결부 성능검증 실물 재하실험 분석

초록

The excavating ground with installation of temporary structures and lining is general construction method for installation of an near-surface underground box-structure in the downtown road. As this general method has shortcomings such as lining installation process and long construction period, the research for rapid construction by constructing an underground box-structure applied with precast module structure with Top-down method is in progress. The performance verification experiment was performed using a full-scale loading test for the connection between wall and upper slab and between wall panels of precast module structure. As the result, it is verified that it was not occurred the crack of connection between walls and that it could resist against the load over the performance requirement in the connection between wall and upper slab.
