| 摘 要： | 采用微型花管桩对土体灌浆形成的帷幕墙对隧道地基进行加固。该方法由注浆花管和注浆固结后的土体形成复合基础共同承担隧道墙脚传来的荷载,改变隧道地基地层承载力较低的性能,提高隧道墙脚底部及仰拱与微型桩及帷幕墙共同承载和变形协调的能力,为今后类似工程提供了经验。

| Abstract: | Tunnel foundation is reinforced by the curtain wall formed by grouting into soil with miniature pipe pile. This composite foundation is formed by miniature grouting pipes and consolidated soil after grouting to bear the loads from the foundation of the tunnel wall, in order to change the performance of low bearing capacity of the tunnel foundation floor, improve the joint carring capacity of the toe of tunnel wall and the invert, together with the miniature pipes and the cur- tain wall, as well as their capacity on deformation coordination, which provides reference for similar projects in the fu- ture. |
