摘要
介绍砂土状浅埋隧道围岩加固的一种新方法—高压旋喷桩的方案设计和施工工艺,简述旋喷桩从地表加固隧道围岩的应用情况,总结旋喷桩用于公路浅埋隧道的施工方法及经验。
Schematic design and construction process of a new method high pressure spinning jetting pile are introduced for consolidate surrounding rocks of sand-clay shallow-depthed tunnel. The application that spinning jetting pile is used to consolidate surrounding rock of tunnel from the ground is briefly described. Construction method and experiences for using spinning jetting pile in shallow-depthed tunnel on a road are summarized.
