Centrifugal modeling of continuous shallow tunnels at active normal faults intersection

Both traffic and water conveyance tunnels’ networks are being extended in many earthquake-prone areas as to its faulting sense. Active fault and tunnel intersections lead to an intense coercive displacement of tunnel lining. Here, a series of 1/60 scale centrifuge tests are run on such intersections normal dip-slip fault mechanism. Experimental surface faulting model of 60 degrees is applied on a set of soil and tunnel models through a fault...
