[提要] 總結(jié)了孔壁粗糙度對(duì)嵌巖樁承載力影響的規(guī)律，探討了孔壁粗糙度影響嵌巖樁承載性狀的機(jī)理，分析了影響嵌巖樁孔壁粗糙度的因素，指出改善孔壁粗糙度是提高鉆孔灌注樁承載力的有效途徑。
[關(guān)鍵詞] 嵌巖樁 孔壁粗糙度 承載力 影響 因素The rule of hole side roughness affecting the bearing capacity of rock-socked pile has been summarized, the principle of the effect of hole side roughness to rock-socked pile bearing capacity has been studied. The factors that affect hole side roughness have been analyzed. The result that it is an effective method to increase bored pile bearing capacity by improving hole side roughness has been pointed out.
Keywords: rock-socked pile; hole side roughness; bearing capacity; effect; factor
