[提要] 通過對大直徑嵌巖灌注樁的豎向、水平靜載現(xiàn)場試驗，并結合對其樁身的應變測試、低應變樁身完整性檢測，分析了填土較厚區(qū)域大直徑嵌巖灌注樁的承載力性狀及其影響因素。試驗結果表明，具有一定嵌巖深度的嵌巖灌注樁，樁頂豎向荷載主要由嵌巖段樁側摩阻力承擔，樁身強度是影響水平承載力的主要因素。
[關鍵詞] 嵌巖灌注樁 現(xiàn)場試驗 承載性狀 影響因素Based on the field static load experiment, the strain test and low strain integrity test on the large diameter rock-socketed cast-in-place piles, the bearing capacity of the large diameter rock-socketed piles in the area where the filling soil is very deep and its effect factors have been studied. The results indicate that the vertical loads on the top of the pile which rock-socketed length is long enough are mainly borne by the frication between the embedded rock part of the piles and soil, and the strength of the piles are the main effect factor of the horizontal bearing capability.
Keywords: rock-socketed cast-in-place pile; experiment; bearing behavior; effect factor參 考 文 獻
