Paper Title:
Study on Surrounding Rock Deformation Discipline of Extra-Large Section Super-Shallow-Buried Tunnel
  Abstract

The type B section of Hongqihegou station is cross section and its excavation section area is about 730 m2. This section is located in rail transit line 3 at the center of Chongqing. For this reason, the heavy traffic, large amount buildings and pipelines surrounding, super-shallow-buried depth and small cross-cover ratio (only 0.4) become the determinant factor in tunnel construction. By using a new method—the up-down sidewall drift method combined with first-wall-and-then-arch method, the Hongqihegou station was successfully completed. Through the analysis of the monitoring measurement data, the discipline of surrounding rock deformation during construction is revealed.
