On　the　basis　of　the　time-domain　wave　method　combined　with　the　explicit　finite　element　method　and　the　viscous-elastic　artificial　boundary　condition,　a　simplified　seismic　wave　input　method　for　near-field　wave　analysis　was　proposed.　With　this　approach,　the　near-field　model　was　stratified　in　the　height　direction,　and　then　the　seismic　motion　was　converted　into　stresses　acted　on　the　viscous-elastic　artificial　boundary　to　realize　seismic　wave　input.　Compared　with　the　equivalent　node　force　input　method,　the　new　method　simplified　the　antecedent　processing　with　an　acceptable　accuracy.　The　numerical　results　obtained　from　a　free　ground　model　indicated　that　when　the　stratified　size　equals　the　maximum　size　of　the　element　mesh　in　dynamical　analysis,　the　accuracy　of　the　simplified　method　is　the　same　as　that　of　the　equivalent　node　method;　when　the　local　parts　of　the　near-field　model　were　stratified　with　the　maximum　element　mesn　size　of　dynamical　analysis　while　the　other　parts　were　stratified　with　a　lager　size,　the　dynamic　responses　of　the　local　parts　have　a　higher　accuracy.　Moreover,　the　dynamic　response　computation　results　of　a　rock　tunnel　demonstrated　the　effectiveness　of　the　proposed　simplified　approach.　©,　2015,　Chinese　Vibration　Engineering　Society.　All　right　reserved.
