Abstract: Taking a drainage tunnel as the research object, FLAC^{3 D} was used to establish an analysis model to analyze the influence of tunnel burial depth on the excavation deformation of shallow tunnel under the condition of primary support. And the results were compared with the field monitoring data. The results show the following characteristics. Firstly, along the direction of excavation, the deformation of surrounding rock can be divided into three stages, and the deformations of three st... More
