With　the　development　of　the　technique　for　constructing　the　cast-in-place　piles　with　high　frequency　vibratory　hammers,　the　cast-in-place　piles　have　been　widely　used　in　construction　engineering.　The　penetration　mechanism　of　the　pile　sleeve　driven　by　high　frequency　vibratory　hammers　remains　unclear,　and　particularly　the　squeezing　effect　in　the　sleeve　penetration　has　yet　to　be　investigated.　In　this　paper,　a　finite　elements　and　infinite　elements　coupling　model　is　developed　for　simulating　the　sleeve　penetration　process　driven　by　high　frequency　vibratory　hammers,　and　used　to　study　the　squeezing　effects　such　as　ground　heaves,　lateral　soil　displacement　and　excess　pore　pressure　generation.　The　results　indicate　that　the　horizontal　displacement　induced　by　soil　compaction　increases　with　the　increase　of　sleeve　penetration　depth,　and　for　the　vertical　compaction　displacement,　the　heave　increases　in　shallow　soil　layers　and　the　settlement　increases　in　deep　soil　layers　as　the　sleeve　penetration　depth　increases.　The　maximum　compaction　displacement　lags　behind　the　sleeve　penetration　depth.　The　reason　for　heave　in　shallow　soil　layers　is　that　the　horizontal　stress　increment　causes　an　increase　in　the　vertical　stress,　and　the　depth　of　heave　interface　increases　with　the　increase　of　dynamical　load　amplitude,　while　decreases　with　the　increase　of　vibration　frequency.　The　excess　pore　pressure　increases　with　the　increase　of　sleeve　penetration　depth,　and　exhibits　an　exponential　attenuation　trend　as　the　radial　distances　increases.　©　2015,　Academia　Sinica.　All　right　reserved.
