(南京市市政設計研究院 210008)[提要] 結(jié)合筆者在南京地區(qū)多項人工挖孔嵌巖灌注樁的設計與試驗實踐,對目前常用的設計公式作了分析研究,提出了較為實用的單樁豎向承載力的算式及參數(shù),并作了較詳細的論述。
[關鍵詞] 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.
