摘　　要：以厦蓉高速(贵州境)榕江格龙—都匀段计摆隧道都匀端右线洞口浅埋段为研究对象,基于监控量测信息包括收敛位移、拱顶下沉、地表位移及断面轮廓等,准确的获取该段围岩变形特征,为施工决策提供科学依据。The study object in this paper is the buried superficially section of right tunnel at Duyun end of the Xia-Rong highway（in Guizhou） Rongjianggelong to Duyun,based on the monitor measuring information include convergence displacement,crown settlement,surface displacement and section contour,the surrounding rock deformation featurest is acquired accurately to provide the scientific basis for construction decision.

关 键 词：浅埋 变形特征 监控量测 施工决策
