综合管廊工程中软土地基处理的施工技术

Construction Technology of Soft Soil Foundation Treatment in Utility Tunnel Project

摘要:

依托城市综合管廊实体工程案例，针对管廊基底软土地基处理问题，介绍了压气旋喷式水泥搅拌桩加固技术，并通过对地基沉降量进行计算，分析了地基处理加固前后的沉降变形规律，论证了管廊软土地基浅层加固技术能有效地降低工后沉降，以期对类似工程施工提供参考和借鉴。

Abstract:

Relying on the solid engineering case of urban utility tunnel, and aiming at the treatment of soft soil foundation of utility tunnel basement, the reinforcement technology of compressed air rotary jet cement mixing pile is introduced. And by calculating and analyzing the settlement deformation law of the foundation before and after treatment and reinforcement, the shallow reinforcement technology of soft soil foundation of utility tunnel can effectively reduce the post-construction settlement in order to provide the reference for the construction of similar projects.
