| Abstract: | Through continuous settlement observation and analysis of the surface of one tunnel entrance, this paper draws surface settlement law of the shallow buried part of tunnel entrance initially supported. By observing and analyzing the sedimentation rate and cumulative settlement at the observation point, it summarizes the subsidence characteristics of the shallow buried parts with poor geological conditions, which is helpful for the tunnel support design with similar geological conditions. |
