[提要]  結(jié)合筆者在南京地區(qū)多項(xiàng)人工挖孔嵌巖灌注樁的設(shè)計(jì)與試驗(yàn)實(shí)踐，對(duì)目前常用的設(shè)計(jì)公式作了分析研究，提出了較為實(shí)用的單樁豎向承載力的算式及參數(shù)，并作了較詳細(xì)的論述。
[關(guān)鍵詞]  人工挖孔樁 嵌巖樁 豎向承載力 分析研究

On the basis of practices of designing and testing on embedded rock concrete piles with man-made hole adopted in Nanjing District presently, the formulae of calculation are analysed and studied. More useful calculation formulae and parameters are discussed in detail.
Keywords: embedded rock concrete piles; digged piles; vertical load; bearing capacity; analysis; study
