New methods of safety evaluation for rock/soil mass surrounding tunnel under earthquake

The objective of this work is to obtain the seismic safety coefficient and fracture surface and proceed with the seismic safety evaluation for the rock mass or soil mass surrounding a tunnel, and the limitation of evaluating seismic stability is considered using the pseudo-static strength reduction. By using the finite element software ANSYS and the strength reduction method, new methods of seismic safety evaluation for the rock mass or soil...
