| 摘 要： | 树根桩在工程中有着广泛的应用,由于其计算理论发展的滞后,导致了在隧道基底加固中应用缓慢,目前国内外软土地基加固中,仍然需要采用现场试验的方法来确定特定条件下的加固效果以及设计参数的合理性。文章针对某一特定黄土隧道的地基承载力试验,得到树根桩加固效果的评价。

| Abstract: | Root pile has a widespread application in the project,but it is slow in reinforcing loess tunnel basis,due to file over of its calculation theory development.Field test is still used to evaluate treatment effect and design variable rationality in soft foundation reinforcement.In this paper,the result of root pile reinforcement is appraised by bearing capacity test of a special loess tunnel's ground. |

| Keywords: | root pile composite foundation soft soil reinforcement |
