Study on the Response of Tunnel Lining under Fault Dislocation

In order to clarify the influence of fault dislocation on tunnel lining, FEM and single factor variable methods were used explore degree dislocation, dip angle, width, intersection angle between strike axis, form lining structure response, based which length anti-dislocation set-up for engineering design was obtained. The research shows that maximum displacement is basically consistent with displacement; increase overall fortification range increases. Among three types axial force caused by reverse largest, level normal moderate, strike-slip smallest. With gradually changes from tension-shear failure shear failure. It suggested should cross at a large as far possible. If it unavoidable when selecting route in project, axis be selected vertically
