Abstract
Nowadays,numericalmodellingisincreasinglyusedtoassessthestabilityoftunnelsandundergroundcav-erns. However, an analysis of the mechanical behaviour of existing brick-lined tunnels remains challengingdue to the complex material components. In order to study the mechanical behaviour of the masonry inbrick-lined tunnels, this paper reports a series of small scale physical tunnel model tests to represent thetrue behaviour of a real tunnel under extreme loading. Advanced monitoring techniques of laser scanningand photogrammetry are used to record tunnel deformation and lining defects. This investigation showshow these techniques may substitute or supplement the conventional monitoring procedures. Moreover,numerical analyses based on continuum and discontinuum approaches are carried out. The numericalresults are compared with physical model tests to assess the overall stability of these tunnels. Predictionsusing numerical models under various conditions have also been carried out to show the mechanicalbehaviour of masonry tunnel and to quantify the influence of the boundary and loading conditions.
