Abstract

Tunnel modelling in the field of geotechnical engineering essentially requires models of tunnelling machines and the simulation of tunnelling processes to clarify the detailed behaviour of tunnel construction. Modern advanced mechatronics, including construction processes, machinining and control technologies, are making it possible to fabricate such models. These technologies, however, are essentially developed in a gravity field condition and are needed to examine in a 1g or cenrifuge field condition. This paper presents the simulation method for tunnelling processes and the design method for tunnelling machines with special reference to the problem of earth pressure acting on the lining of a shield tunnel. The paper then introduces and verifies the design method for tunnelling machines in the 1g field by means of checking the reproduceability of experiment data and their comparison with data in the field.

지반공학적인 측면에서의 터널에 대한 모델링작업은 실질적인 터널공사시 야기되는 상세거동을 재현할수 있는 터널장비의 개발로 터널굴진과정을 실질적으로 묘사하는데 있다고 볼수 있다. 최신기계정보활용기술은 즉 시공과정 및 기계제어기술등을 실험실에서 재현할 수 있도록 하였다. 그러나, 이러한 기술 등은 중력장상태에서 사용되도록 개발되어지고, 1g 또는 원심장 (Centrifuge Field)상태의 실험에서 주로 활용되고 있다. 이에 따라 본 논문은 터널링과정에 대한 씨뮬레이션기법과 실험실에서 활용되는 쉴드터널장비의 설계기법 및 개발에 대한 연구 결과를 수록하였다. 또한 개발된 장비의 정밀성과 신뢰성을 반복적인 실험을 통하여 검증하고, 개발된 장비를 이용하여 얻은 결과와 실질적인 현장자료와 비교분석하였다.
