摘要
通过对某隧道洞口处地表沉降的连续观测分析,得出初期支护后的隧道洞口浅埋段地表沉降规律;通过对布测观测点的沉降速率、累计沉降观测分析,总结出地质较差隧道浅埋段的沉降特点,为同类地质条件的隧道支护设计提供参考。
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.
