摘要结合工程实践，对连拱隧道施工中边坡变形进行相关监测，分析连拱隧道边坡三维变形随时间变化规律、空间分布规律及不同开挖工序引起的边坡变形特征。分析结果表明：(1) 边坡位移三维特征明显；(2) 边坡位移受隧道开挖扰动影响大；(3) 左、右洞上台阶开挖对边坡变形影响较大，为边坡变形控制的关键点；(4) 左洞上台阶和右洞下台阶开挖对边坡纵向的影响范围约为隧道跨度的2倍，右洞上台阶及左洞下台阶的影响范围约为隧道跨度的1/2。这些研究结论可为类似条件下连拱隧道边坡设计、施工和现场监测提供参考。

Abstract：Based on the engineering practice of a twin-arch tunnel，the monitoring of surrounding rock deformation during the tunnel construction is carried out. The change characteristics of 3D slope deformation in twin-arch tunnel with time and its spatial distribution law，and the slope deformation characteristics induced by different excavation procedures are analyzed. The analysis results indicate that：(1) The deformation of tunnel slope presents obvious 3D characteristics；(2) The slope deformation can be great influenced by tunnel excavation；(3) The excavations of the upper bench in the left and right carven have a great effect on the slope deformation during the construction of twin-arch tunnel；(4) The longitudinal influence area induced by the excavation of the upper bench of the left carven and the down bench of the right carven is about 2 times of tunnel span；and the influence area induced by the excavation of the upper bench of the right carven and the down bench of the left carven is about one half of the tunnel span. These presented conclusions can provide references for the design，construction and site monitoring of twin-arch tunnels in similar conditions.
