Based　on　lots　of　vertical　loading　test　results　of　pile　foundations,　a　load　transfer　method　is　put　forward　to　predict　the　vertical　bearing　capacity　of　the　long　bored　pile　in　the　heterogeneous　strata　in　Beijing　area.　Compared　with　the　previous　methods,　this　load　transfer　method　is　modified　considering　the　effects　of　heterogeneous　strata,　the　depth　of　the　soil　around　the　pile,　and　the　post-grouting　technique.　An　optimized　method　for　defining　the　load　transfer　parameters　and　a　predicting　method　for　ultimate　vertical　bearing　capacity　are　also　established.　The　calculated　result　from　a　case　study　shows　that　the　vertical　load　transfer　behavior　calculated　using　this　newly　developed　method　fit　the　test　results　very　well.　It　can　be　used　to　estimate　the　ultimate　vertical　bearing　capacity　of　a　single　pile　reliably　in　the　heterogeneous　strata.
