Abstract

This paper describes a study of the influence of shield tunnel construction on the displacements and stresses induced in the linings of existing nearby parallel tunnels. The paper presents a brief review of a set of laboratory scale model research programme investigating the influence of tunnel proximity and alignment, liner stiffness on the nature of the interactions between closely spaced tunnels in clay. A total of two sets of carefully controlled physical model tests were performed. A cylindrical test tank was developed and used to produce clay samples of Speswhite kaolin. In each of the tests, three model tunnels were installed in order to conduct two interaction exts that have been carried out to investigate the interaction problem between parallel tunnels. The results of these tests are compared with the results of finite element analysis to investigate the techniques that must be used to obtain reliable numerical solutions to this type of problem.

이 연구는 기존터널과 근접하여 새로운 터널을 시공할 경우 이에 따른 터널의 상호거동에 대한 연구이다. 특히 이 연구는 연약지반내에서의 근접터널 시공에 따른 기존터널 라이닝의 변위 및 응력 영향에 대하여 수행되었다. 이와 같은 터널거동을 연구하기 위하여 시험실 모형시험을 수행하였다. 이 시험 결과는 터널의 상호 거동에 대한 보다 정확한 결과를 얻기 위한 시뮬레이숀 기법 개발을 위하여 유한요소기법을 이용하여 수치해석을 수행하여 비교 분석하였다.
