（交通部第一航務工程設計院 天津 300222）[提要] 通過二組大直徑鉆（沖）孔灌注樁的垂直靜載試驗，分析了大直徑鉆孔灌注嵌巖樁和非嵌巖樁的荷載傳遞規(guī)律和垂直承載力性狀，并提供了一些巖土極限側(cè)摩阻力和極限端阻力，供今后設計同類型樁時參考。
[關(guān)鍵詞] 大直徑鉆（沖）孔灌注樁 嵌巖樁 摩擦樁 端承樁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
