Abstract

The interaction analysis and evaluation on tunnel passing through underlying vacant areas is essential in highway construction. A 3D numerical model of tunnel at underlying vacant area has been established to analysis the deformation and mechanical characteristic of tunnel structures. According to the analysis of displacement of tunnel, the significant lateral influence range of vacant area on tunnels is about 25 m from the center line of vacant area. And the main longitudinal effect distance of vacant area construction on tunnel is about 30 m before and after from the working face of vacant area to tunnel. In this range, some monitoring and strengthening support measures should be taken into consideration. The conclusions presented can provide reference for the design and construction of similar engineering at underground vacant areas.
