Abstract The shallow-depth subsurface excavation method used in recent years by more and more underground engineering projects. The cut -and -cover method and the shield method have become one of the main construction methods for underground projects, but it is rare at home to employ the subsurface method where the extra-shallow depth stratum passes through existing lines. This article emphatically introduces the focal control points and quality supervisory measures taken by the project supervision office of our corporation in adopting, based on the features of the project and the cardinal principle of the New Austrian Method, the extra -shallow depth subsurface excavation method during the supervision of construction of the underpass beneath the Changchun north station building. By way of the effective supervision and control, the underpass successfully runs through the existing lines, ensuring the safety of railway operation, and at the same time helping the project reach the standard of excellence in quality, which has accumulated experience in the quality control over the construction traversing exiting lines with the extra -shallow depth subsurface method. The completion of the project is highly spoken by the employer and people from all walks of life.
