초록
본 연구에서는 다양한 근접굴착 시공 조건과 각 충격에 대한 민감도에 대한 매개변수 분석을 수행하였다. 연구결과는 향후 터널과 근접한 건설사업의 근접성 평가에 활용할 수 있을 것으로 분석되었다. 특히 측벽의 시공 조건에서 터널 직경의 약 1.0배 정도로 터널의 안정성에 큰 영향을 받는 것으로 나타났다. 이러한 영향을 최소화하기 위해서는 벽체의 강성을 높이는 것이 매우 효과적이며, 운영 시 지하시설물의 장기 건전성 확보에도 유리한 것으로 판단됨을 확인하였다.
Abstract
Parameter analysies of various close excavation construction conditions and sensitivity to each impact have been done to evaluate the proximity of construction projects close to tunnels in the future. As a result, it was found that the stability of the tunnel was significantly affected by about 1.0 times the diameter of the tunnel, especially under the construction conditions of the sidewall. In order to minimize this impact, it has been confirmed that increasing the rigidity of the wall is very effective, and it is also considered advantageous to secure the long-term soundness of underground facilities during operation.
