| Abstract: | Aiming at the problem of structure design of a highway tunnel crossing active faults zone,protective design strategies of breaking resistance are put forward;and then over-excavation and articulated design are discussed.The calculation methods of the length of the single segment geometry and the shear stiffness of the joints are proposed.In addition,tunnel element kinematics after joint rupture is analyzed. |
