摘　　要：本文结合工程实例,对人工挖孔嵌岩扩底抗拔桩设计机理、抗拔承载力计算、桩身配筋、检测等四个问题进行了详细探讨。在此基础上,并把嵌岩扩底抗拔桩与常规抗拔桩进行了比较。分析结果表明:对于该场土嵌岩扩底抗拔桩更经济合理,可供类似工程参考。Four problems which are the basic principle, the calculation of uplift bearing capacity, the reinforcement, the testing are encountered in the design of the set - into - rocked manaul holing uplift piles with enlarged bottom. Analysis and interpretations are based on the actual project. Furthermore, the results show that it is more reasonable and economical than the normal uplift piles in such site soil. And it can be used for reference by similar projects.
