Analysis of the Impacts of a Tunnel on a Normal Fault Rupture through Uniform Soil Cover

Damages due to a fault activity can be divided into dynamic rupture and quasi-static rupture. In some special projects like roads, channels, and pipelines, engineers have to design and construct them on the faults inescapably. In addition to seismic design, the effects of fault rupture crossing the structures must be considered in the design process. In this paper, four different computer models of a granular alluvium with and without a tunnel were made by a three-dimensional finite-difference software. A normal fault offset with three different cross angles was applied to the bottom of the models at the next step. Then, the shear bands propagation and ground deformations were calculated. The results show that the effects of tunnel existence on the ground deformations and shear band propagation depend on the cross angle.
