The　problem　of　pile　foundation　response　to　impact　loading　on　adjacent　field　is　a　dynamic　interaction　of　the　whole　system　consisting　of　piles　and　soil　under　the　impact　load.　To　study　the　potential　vibration　of　the　pile　foundation　affected　by　impact　loading　on　adjacent　field,　the　vibration　is　simulated　with　finite　element　method　(FEM).　Using　FEM　software　of　ABAQUS　a　coupled　finite　element-infinite　element　(FE-IFE)　model　is　created;　the　pile　foundation　response　to　impact　loading　on　adjacent　field　is　analyzed;　then　the　factors　affected　pile　foundation　response　are　considered;　some　useful　conclusions　are　drawn;　the　value　of　vibration　amplitude　is　determined　by　energy　of　impact　loading　and　distance　between　pile　foundation　and　impact　site;　and　the　wavelength　of　pile　foundation　vibration　is　determined　by　distance　between　pile　foundation　and　impact　site.
