Consideration of Mechanical Characteristic for Tunnel Lining

Abstract

Tunnel lining is designed and constructed mainly based on the past experience. Considering mechanical characteristic and the introduction of new materials to lining lead to a proper structure, and it can reduce the cost of construction. In this study, full-scale loading experiment for tunnel lining was carried out to achieve the upper purposes, and the analysis was done on the basis of the results. The following results were acquired:(1) the cracks were dispersed in the forecasting area in the lining with SFRC, (2) in analysis, the bending moment decreased considering the influence of crack in lining, while the axial force was nearly constant in the same load.
