摘要
结合深圳地铁5号线西丽站-大学城站区间风道高压水平旋喷桩超前预加固技术的工程实践，重点介绍了水平旋喷桩的加固机理、施工工艺、技术要点和效果，为以后富水软弱围岩暗挖隧道拱部和掌子面超前预加固技术提供了很好的借鉴。
In combination with the engineering practice of advanced pre-reinforcement of high pressure horizontal rotating jet grouting pile for air duct of Shengzhen subway No.5 line Xili station-University station, the reinforcement mechanism for rotating jet grouting pile, the construction technique, technical essentials and effect were introduced,and reference was provided for adavaneded pre-inforeement technology of future underground excavated tunnel arch and face with much water and weak surrounding rocks.
