| 摘 要： | 本文通过17组试桩的原型荷载试验及计算，对新型挤压分支桩的承载能力进行了计算分析与研究。结果证明：同一场地、相同桩长、相同桩径的新型挤压分支桩比钻孔灌注旺的单桩竖向承载力要提高一倍以上（混凝土量仅增加6％～12％）。因此，新型挤压分支桩是一种技术经济效益十分显著的新桩型，值得工程界的广泛重视。

| Abstract: | In this paper, the bearing capacity of a new type compaction pile with expanded branches hasbeen analyzed based on the prototype test and calculation results of seventeen test piles. It is foundthat the bearing capacity of such a pile can be increased more than twice of that of the commonlyused bored pile in the same foundation soil, with the same diameter and lenglh. Therefore, it isworthwhlle for engineering circles to pay more attention to this kind of piles due to their effi -ciency both in technology and economy. |
