Abstract：

The　stiffness　and　damping　matrixes　of　3D　consistent　artificial　boundary　are　deduced　through　viscous-spring　artificial　boundary　theory.　3D　equivalent　viscous-spring　artificial　boundary　element　is　developed　by　comparing　the　matrixes　of　general　finite　element　and　consistent　viscous-spring　artificial　boundary.　This　boundary　element　is　applied　to　uniform　and　layered　half　space　problems,　respectively.　The　results　show　that　3D　equivalent　viscous-spring　boundary　element　has　the　same　precision　as　viscous-spring　artificial　boundary,　and　the　former　is　more　applicable　and　simple.
