[提要] 根據(jù)軟土地基大直徑鉆孔灌注樁豎向承載力的現(xiàn)場試驗結(jié)果，分析樁的豎向承載性狀、樁側(cè)阻力的變化規(guī)律及影響因素，為合理利用該樁型提供一定的理論依據(jù)。
[關(guān)鍵詞] 大直徑鉆孔灌注樁 軟土地基 豎向承載性狀 側(cè)阻力 單樁極限承載力On the basis of the in-situ test data of large diameter cast-in-place pile in soft foundation, the behavior of vertical bearing capacity, skin friction, and the influencing factors are analyzed. The results provide certain theory basis for further reasonable application of this kind of piles.
Keywords: large diameter cast-in-place pile; soft foundation; vertical bearing behavior; skin friction; limit bearing capacity
