초록

최근 고도의 경제성장으로 인한 도시화와 바른 산업발달은 지하공간의 확장 뿐만 아니라 이용 및 최적화를 필요로 한다. 지하시설물이나 근접구조물의 피해 및 침하와 같은 많은 문제점을 일으키는 흙막이구조물을 위한 버팀굴착의 지역에서 넓고 깊은 기초가 건설되고 있다. 본 연구는 5개의 굴착 공사현장으로부터 얻어진 측정결과에 근거한 침하량과 침하의 영향거리에 관하여 고 하였다. 굴착깊이를 이용한 최대지표침하량(0.28∼0.3)(%)H는 계측값 및 Clough방법에 의한 값과 유사성을 갖으며 Clough 방법에 의한 침하량 및 침하영향거리의 산정이 가장 합리적임을 알 수 있다.

Recently, the rapid industrialization and urbanization of the country due to a high economic growth, require optimization, usage and the expansion of underground space. Therefore the consturction of large and deep basements takes place in braced excavated area where their earth retaining structures cause many problems such as settlement and damages of nearby buildings and underground utilities. this study deals with the influence distance of settlement and the amount for settlement based on the measurement which were obtained at five excavation construction sites. Maximum ground surface settlement, (0.28∼0.3)(%)H utilizing depth, is similar to the measurement and the value by Clough's method. It was found that the settlement and the influence distance of settlement calculated by Clough's method were rational.
