| 中文摘要: |
| 本文结合中国中材国际工程股份有限公司总承包工程，通过对扩底人工挖孔灌注桩和采用后注浆技术的人工挖孔灌注桩的比对，说明设计采用灌注桩后注浆技术虽然增加了桩的数量，但明显减少了混凝土和钢筋的总体使用量，从而降低了工程成本。 |
| 英文摘要: |
| This paper combines the general contract project by Sinoma International Engineering Co.，Ltd. Comparing the expansion bottom of hand-dug cast-in-place pile with the post-grouting technology of hand-dug cast-in-place pile， the results show the design uses the post-grouting technology will slightly increase the number of piles， but will reduce the overall amount of concrete and steel significantly， thereby reducing the cost of the project. |
