| 摘 要： | 为了提高人工挖孔桩入岩的爆破单循环进尺,在实际工程中进行了不同布孔方式和起爆方式的现场试验,得出中心掏槽布孔,周边孔对称起爆的爆破方法最佳;同时对炮孔深度也进行了探讨,得出炮孔深度最好为桩径的1倍左右。

| Abstract: | To improve blasting-cycle footage of hand-dug pile in rock,different methods of defining pile's position and blasting were test.The center cutting method was carried out.And symmetrical blasting was the best way.At the same time,the cannon hole's depth was discussed.It suggested that the best depth of cannon hole is the same diameter with pile. |
