Abstract

It is analyzed the risk of building damage due to ground surface subsidence occurred during constructing a tunnel below buildings in sand-gravel layer. The overburden and the thickness of sand-gravel layer is about 20m and the width and the height of the tunnel are 12m and 8.6m, respectively. The tunnel is pre-reinforced by umbrella method with three rows of long steel pipes and grouting. Surface subsidence is measured at 36 points surrounding buildings and measured data are used to calculate optimized three dimensional subsidence surface. Depending on the building location, deflection ratio and horizontal strain are calculated to evaluate the risk of building damage. No damage occurs at the buildings because of both the small deflection ratios involved 1~4mm subsidence and compressive horizontal strains.

모래자갈층에서 터널굴착 시 발생하는 지표침하에 의해 지상빌딩에 발생하는 손상도를 분석하였다. 모래자갈층의 두께와 터널까지의 심도는 약 20m이고 터널의 폭과 높이는 각각 12m, 8.6m이다. 터널은 막장전방을 3열의 강관다단그라우팅으로 보강하면서 시공하였다. 터널시공 중에 빌딩주변 36개소에서 지표침하를 계측하였고 이를 이용하여 3차원 지표침하면을 구하고 빌딩의 위치에 따라 처짐비와 수평변형율로 빌딩의 손상도를 평가하였다. 시공 중 계측된 지표침하는 약 1~4mm로 작았고 빌딩은 수평압축변형을 받는 상태가 되어 빌딩에 손상이 발생하지 않았다.
