When　tunnel　passes　through　fracture　zone　in　an　orthogonal　manner,　the　embedded　depth　plays　a　crucial　role　in　seismic　response　of　tunnel.　This　article,　by　numerical　simulation,　respectively　calculates　the　speed　and　acceleration　as　well　as　the　scope　of　plastic　zone　on　key　points　of　tunnel　lining　structure　and　also　makes　the　comparison　when　the　embedded　depth　is　respectively　2D,　5D　and　8D　and　when　the　surrounding　rock　grade　is　Grade　IV　and　the　width　of　fault　fracture　zone　is　10　m.　The　study　shows　that,　when　the　embedded　depth　is　8D,　the　dynamic　response　of　tunnel　is　respectively　smaller,　and　the　influence　of　fault　fracture　zone　is　less;　when　the　embedded　depth　is　2D,　the　dynamic　response　of　tunnels　through　fault　fracture　zone　is　significantly　greater　than　that　without　fault　fracture　zone,　and　the　lining　structure　is　dominated　by　shear　fracture.　©　2016　Taylor　&　Francis　Group,　London.
