초록

본 연구에서는 흙막이 가시설 공법중 지반의 변위를 억제하고, 토공사 및 구조물 공사의 시공성을 크게 개선한 IPS 흙막이 가시설 공법을 시공한 현장의 계측자료를 바탕으로, 탄소성보법 수치해석 프로그램(EXCAV/W)을 이용하여 수치해석을 실시하였다. 그 결과, 선행하중을 가한 해석치가 평균 13.2% 감소하였으며, 또한 일반적인 해석치보다 현장 계측치는 평균 26.7% 감소하는 것으로 나타났다. 따라서 IPS 흙막이 가시설 공법은 기존 버팀보 공법에 흙막이벽의 수평변위에 대한 안전성을 확보하고 있음을 알 수 있다. 또한 IPS 흙막이 가시설 공법을 이용한 선행하중 효과를 통해 수평변위가 감소하는 것을 확인할 수 있다.

In this study, gathered measuring data at fields constructed by IPS(Innovative Prestressed Support) system controls the ground displacement and improves the constructability of earth work and structure work greatly, and compared with horizontal displacement calculated by Elasto-plastic analysis program(EXCAV/W). As the result, displacement of calculated by pre-loading data is reduced 13.2% average of general method, and measuring displacement is also reduced 26.7% average of general method. Therefore that IPS system is more safe than conventional strut method in contrast to displacement of underground wall. In addition, horizontal displacement is reduced through the pre-loading effect used by IPS system.
