摘要: Pipe-roof has been adopted extensively as pre-support in tunnel construction. The vertical deformations of the pipe-roofs entrance Liuyanghe Tunnel are monitored by installation a series strain gauges to investigate mechanical behavior during excavation. Based on monitoring results, characteristics and evaluation reinforced effect pipe-roof construction process were analyzed.
