Multi-scale　finite　element　(FE)　modeling　is　an　effective　method　to　balance　the　computational　efficiency　and　accuracy　using　different　elements　to　simulate　different　parts　of　structures　considering　the　demands　of　engineering　practice.　In　order　to　analyze　the　earthquake-induced　damage　and　collapse　of　Gaoyuan　bridge　in　Wenchuan　earthquake,　the　simplified　rigid　surface　coupling　method　is　developed　to　achieve　the　coupling　between　solid　element　and　beam　element　based　on　LS-DYNA　program　at　this　study.　The　numerical　results　have　shown　that　the　failure　of　A2　abutment　and　strong　pounding　force　cause　the　bridge　superstructure　lost　longitudinal　constraints,　and　the　girders　of　the　third　span　and　forth　span　fell　down　due　to　oversize　longitudinal　displacement.　Obviously,　the　multi-scale　FE　modeling　is　a　high-efficiently　analytical　method　for　simulating　local　damage　and　even　collapse　of　bridges　structures　under　strong　earthquake　excitations.　The　inclined　degree　of　bridge　bents　and　the　damage　of　concrete　in　different　bridge　piers　using　the　multi-scale　FE　modeling　method　improved　in　this　paper　agrees　well　with　actual　earthquake　damage　of　Gaoyuan　highway　bridge.
