摘　　要：针对碳纤维补强公路隧道衬砌,按荷载结构法,以碳纤维补强钢筋混凝土偏压构件的理论为基础,提出了裂缝发展分析方法,初步形成了一套适用于碳纤维补强公路隧道衬砌结构的设计计算方法。可为碳纤维加固修补公路隧道衬砌结构提供设计依据。In view of the quality defects encountered in lining of highway tunnel reinforced with carbon fiber sheet and based upon the theory of eccentrically compressed RC members reinforced with carbon fiber sheet and load structure method analysis method of crack propagation is proposed. In addition, one calculation method is obtained, which is suit to lining structure design of highway tunnel reinforced with carbon fiber sheet and provide good references for similar works.
