The　objective　of　this　work　is　to　obtain　the　seismic　safety　coefficient　and　fracture　surface　and　proceed　with　the　seismic　safety　evaluation　for　the　rock　mass　or　soil　mass　surrounding　a　tunnel,　and　the　limitation　of　evaluating　seismic　stability　is　considered　using　the　pseudo-static　strength　reduction.　By　using　the　finite　element　software　ANSYS　and　the　strength　reduction　method,　new　methods　of　seismic　safety　evaluation　for　the　rock　mass　or　soil　mass　surrounding　a　tunnel　are　put　forward,　such　as　the　dynamic　finite　element　static　shear　strength　reduction　method　and　dynamic　finite　element　shear　strength　reduction　method.　In　order　to　prove　the　feasibility　of　the　proposed　methods,　the　results　of　numerical　examples　are　compared　with　that　of　the　pseudo-static　strength　reduction　method.　The　results　show　that　1)　the　two　methods　are　both　feasible,　and　the　plastic　zone　first　appears　near　the　bottom　corners;　2)　the　safety　factor　of　new　method　II　is　smaller　than　that　of　new　method　I　but　generally,　and　the　difference　is　very　small.　Therefore,　in　order　to　ensure　the　safety　of　the　structure,　two　new　methods　are　proposed　to　evaluate　the　seismic　stability　of　the　rock　mass　or　soil　mass　surrounding　a　tunnel.　A　theoretical　basis　is　provided　for　the　seismic　stability　of　the　rock　mass　or　soil　mass　and　the　lining　surrounding　a　tunnel　and　also　provided　for　the　engineering　application.
