摘要

以厦漳公路（厦门段）东孚隧道施工为例，介绍了?229大管棚跟管钻进咬合相接加固技术+十字交叉隔壁后拆式开挖技术在浅埋富水软弱土层隧道开挖过程中的应用；同时利用TGMIS动态智能化监测系统对施工沉降状况进行了数据采集、分析及处理，使围岩变形得到控制，顺利通过了浅埋软弱土层段掘进施工。

Abstract

This article takes Xia-Zhang highway (Xiamen section) Dongfu tunnel construction as an example. Introduces the application of ?299 big pipe follow with pipe drilling occlusal and linking reinforcement technology+cross-located right next door after disassembly type excavation technology in shallow-buried rich water soft soil stratum tunnel excavation process. While using TGMIS dynamic intelligent monitoring system of construction settlement conditions for data acquisition， analysis and processing， make the deformation of surrounding rock control， successfully passed the construction of shallow-buried soft soil excavation.
