[提要]  通过二组大直径钻（冲）孔灌注桩的垂直静载试验，分析了大直径钻孔灌注嵌岩桩和非嵌岩桩的荷载传递规律和垂直承载力性状，并提供了一些岩土极限侧摩阻力和极限端阻力，供今后设计同类型桩时参考。

Through static loading tests of large diameter rock socketed bored cast-in-situ piles in groups, the author analyzes the bearing capacity behaviour and load transferring characteristics of large diameter rock socketed and nonsocketed bored cast-in-situ piles and presents limiting values of side friction and base resistance of some rocks, which can give reference for design.
Keywords: large diameter bored cast-in-situ piles; socketed pile; friction pile; bearing pile
