Abstract

The behavior of the masonry lining is studied to gain basic information on how to reinforce the masonry tunnels. Apart from the previous works on the masonry structures, the multi-course masonry structure, realistic in field condition, is considered and the constitutive relationship of the masonry is, therefore, established. The design charts of the orthotropic material properties are proposed according to the stiffness ratio and the crack initiation and subsequent propagation model is also considered to model the brittle nature of the masonry. A numerical analysis on the masonry panel is investigated to verify the proposed model and future works of the masonry lining are briefly explained.

본 연구에서는 재래식 철도터널의 라이닝재로 사용된 조적식 구조물의 해석기법에 대하여 논의하였다. 이를 위하여 기존의 조적식 구조물 모형화 과정과는 다르게 다층 조적조에 대한 해석기법을 제안하였으며 조적의 각종 비등방 물성을 도표화하여 현장에서 손쉽게 적용가능하도록 하였다. 조적조내 균열발생 경우를 고려하여 다층 조적조의 분산형 균열모형을 제안하였으며 균열전파 모형도 함께 고려하였다. 수치해석을 통하여 제안한 모형의 적정성을 검증하였으며 향후 연구방향에 대하여 간단히 언급하였다.
