摘要：

A　reasonable　artificial　boundary　is　very　important　for　the　accurate　calculation　of　wave　propagation　in　energy　opening　system　using　Finite　Element　Method.　In　this　paper,　a　Viscous-spring　Artificial　Boundary　in　saturated　porous　media　is　proposed　to　simulate　the　effect　of　energy　radiation.　Some　springs　and　damps　are　applied　on　the　artificial　boundary　to　reflect　the　wave　spreading　effect　in　solid/fluid　media　respectively,　while　considering　the　interaction　between　the　solid　phase　and　the　fluid　phase.　Numerical　examples　indicate　that　the　proposed　viscous-spring　artificial　boundary　is　appropriate.
