结合襄渝二线(陕西段)杨河隧道西河湾横洞炭质片岩地层施工实例,介绍了隧道围岩收敛变形情况和量测数据分析及施工对策,为今后类似地层施工提供借鉴与参考。
Combined with the construction example of the Hengchuang carbonaceous schist formation in the Yanghe tunnel of the Xianghe second line (Shaanxi section), the convergence and deformation of the surrounding rock of the tunnel and the measurement data analysis and construction countermeasures are introduced, providing reference and reference for similar strata construction in the future.
