Abstract:

Due to the difference of their environments, the deep and shallow buried tunnels show different deformation patterns in the excavation. This paper simulates the deformations of the deep and shallow buried soft rock tunnels with different stress boundary conditions, rock mechanical properties and section shapes of tunnels. The calculation results might be used for the selection of the tunnel section shapes, and the excavation support of tunnels.

Key words:

deep engineering|soft rock tunnel|high ground stress
