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.
