터널 라이닝에 작용하는 하중을 예측하는 것은 터널설계에서 가장 중요한 문제 중의 하나이다. 하지만 수치해석적 방법외의 기존의 해석적 방법들은 터널건설 방법이나 지질학적인 다양성을 충분히 고려하지 않고 있다. 에드몬톤의 터널에서 실제로 측정된 하중을 기존의 해석적 방법을 이용해 얻어진 하중과 비교하였다. 하지만 기존의 방법들은 터널 하중을 예측하는데 만족하지 못한 결과를 보여주고 있다. 터널 라이닝을 설치하기 이전에 터널 전면에서 일어나는 응력 감소를 고려해 주기 위하여 아이젠스타인-네그로의 방법과 기존의 방법을 결합하여 터널 하중을 예측할 것을 제안 하였다.

Abstract

Estimation of loads on tunnel lining is one of the major issues to be addressed in the design of a tunnel. The existing analytical methods do not consider important details of construction and the variation of geology along the tunnel axis. The measured loads obtained from several sanitary and subway tunnels in Edmonton, Alberta, Canada, are compared with the lining loads calculated using the existing analytical methods. However, the existing methods are determined to be not fully satisfactory for the estimation of lining loads. To account for face and heading effects occurring prior to lining installation, the stress reduction factor determined using Eisenstein and Negro's method is used coupled with an analytical solution for calculation of lining loads.
