摘要： 以丹土一级公路03A标伍家岭隧道拱顶沉降实测数据为基础，利用数学方法对其进行回归分析，得到该隧道在开挖过程中围岩变形随时间的变化关系，为后期设计修改与施工指导提供理论依据，同时也为以后隧道的设计、施工积累经验。

Abstract: The regression analysis method can provide an effective guidance for the changes in the tunnel design and construction. This paper presents a case history of the construction displacement monitoring at the top of the Wujialing Tunnel in 03A Bid Document in DanjiangkouTusiya(DanTu)primary highway.During the tunnel excavation,the time effect on the deformation in the New Austria Tunneling Method(NATM)was applied in the construction and the regression analysis was performed on the deflection data collected at the crown of the tunnel.The time relationships with the surrounding rock mass are obtained.These relationships can provide guidance for the subsequent design and construction changes.
