the variations of stress and deformations of wall-rock are complex. It is difficult to construct double-arch tunnel
and it is necessary to perform some technological guidances to assure the of construction safety. Numerical analysis is used to calculate and analyze the stress and deformation of the fractured mountain body. The result shows that in the course of construction
the wall-rock can maintain stable. A theoretical direction and reference is offered to practical performance. And a new method is also offered.
