Base　on　the　Finite　Element　Method　of　near-field　wave　motion　together　with　the　viscous-spring　artificial　boundary　condition,　the　earthquake　wave　motions　can　be　transferred　into　equivalent　nodal　fores　that　applied　on　the　truncated　boundary.　In　the　present　work,　the　formulas　of　equivalent　nodal　forcesfor　the　plane　seismic　SV　waves　with　oblique　incident　directions　are　deduced.　The　accuracy　of　the　input　method　is　demonstrated　by　the　scatting　problem　of　an　infinitely　long　circular　cylindrical　tunnel.　Comparing　with　the　previous　input　method　of　SV　waves,　the　present　method　can　simulate　the　incidence　of　SV　waves　with　an　arbitrary　direction.　Then,　the　proposed　method　is　employed　to　investigate　the　seismic　responses　of　long　lined　tunnels　under　SV　waves　with　different　incident　directions.　The　influence　of　the　incident　direction　of　SV　wave　on　the　plastic　strain,　tensile　and　shear　deformations　along　the　tunnel　axis,　the　out-plane　and　in-plane　deformations　of　the　tunnel　cross-section　is　studied.　The　numerical　results　indicate　that　the　seismic　responses　of　long　lined　tunnels　are　significantly　affected　by　the　incident　directions　of　SV　waves,　which　should　be　included　in　mapping　the　seismic　risk　of　tunnels.　©　2018,　Nanjing　Univ.　of　Aeronautics　an　Astronautics.　All　right　reserved.
