초록

이 논문에서는 역순법 원리를 이용한 역해석 결과를 제시하였다. 국내에서 건설된 두 곳의 지하비축기지 공사 중에 계측한 자료를 이용하여 비축기지 진입터널 주위 암반의 변형계수와 초기 지압을 계산하였다. 역해석에서 얻어진 결과를 입력자를로 하여 유한요소해석을 수행하였으며 그 결과를 계측치와 비교, 검토하였다.

In this paper, the results of back analysis based on, the inverse method are presented. Using the field measurements obtained from the two different underground storage caverns in Korea during their construction, the deformation modulus and the initial in-situ stresses of the rock masses around the access tunnels are calculated. The finite element analysis is carried out by usinB these results as input parameters. The calculated displacements are compared with the measured ones.
