摘　　要：在张石高速公路岔道1#隧道工程中,采用GBW-50型多点位移计、GHB-3型应变计和GJL-3型应力计进行量测,对量测数据进行了分析,掌握了围岩内部位移的运动变化规律及双连拱隧道在浅埋偏压情况下围岩压力及支护应力的分布规律,为后期施工方案的制订提供了依据。Based on the double-arc tunnels engineering of Chadao No.1 on the expressway from Zhangjiakou to Shijiazhuang, the monitoring measurement was studied with GBW-50 displacement meter, GHB-3 Strain gauge and GJL-3 Stress gauge, through the analysis of monitoring measurement, the deformation and movement of country rock in tunnel were obtained. At the same time, the distribution law was obtained about the surrounding rock and support stress. The conclusion has important reference value to similar tunnels.
