During　driving　sleeve　of　cast-in-place　piles　by　vibratory　hammers,　soils　were　squeezed　into　sleeve　and　then　soil　plugging　was　formed.　The　physic-mechanical　properties　of　the　soil　plug　have　direct　influence　on　the　load　transmission　between　the　sleeve　wall　and　soil　plug.　Nevertheless,　the　researches　on　this　issue　are　insufficient.　In　this　study,　finite　element　and　infinite　element　coupling　model　was　introduced,　through　the　commercial　code　ABAQUS,　to　simulate　the　full　penetration　process　of　the　sleeve　driven　from　the　ground　surface　to　the　desired　depth　by　applying　vibratory　hammers.　The　research　results　indicated　that　the　cyclic　shearing　action　decreases　both　in　soil　shear　strength　and　in　granular　cementation　force　when　the　sleeve　is　driven　by　vibratory　hammers,　which　leads　to　a　partially　plugged　mode　of　the　soil　plug　inside　the　sleeve.　Accordingly,　the　penetration　resistance　of　sleeve　driven　by　vibratory　hammers　is　the　smallest　compared　to　those　by　other　installation　methods.　When　driving　the　sleeve,　the　annular　soil　arches　forming　in　the　soil　plug　at　sleeve　end　induce　a　significant　rise　in　the　internal　shaft　resistance.　Moreover,　the　influence　of　vibration　frequencies,　sleeve　diameters,　and　soil　layer　properties　on　the　soil　plug　was　investigated　in　detail,　and　at　the　same　time　improved　formulas　were　brought　forward　to　describe　the　soil　plug　resistance　inside　vibratory　driven　sleeve.
