摘　　要：《混凝土结构加固设计规范》(GB50367-2006)正在修编中。为了配合规范修编工作,就规范中存在的3个比较主要的问题:高强碳纤维片材能否充分利用强度题、体外预应力加固法用低强钢筋补强拉杆的合理性和采用体外预应力加固法加固钢筋混凝土大梁时对原构件混凝土强度最低要求的问题,通过理论分析和结合工程实践提出看法。At present the Design code for strengthening concrete structure(GB50367-2006) was amending,in order to coordinate the revision of design code,the view according to the existing design code through the theoretical analysis and engineering practice from three major problems were put forward: whether high-strength carbon fiber sheet can make full use of the strength in reinforceing the concrete structure,the rationality of using low-strengthen reinforcing rods in externally prestressed reinforcement and the minimum requirements of concrete strength of the reinforced concrete beam by using externally prestressed reinforcement.

关 键 词：规范修编 高强碳纤维片材 体外预应力加固法 低强补强拉杆 最低混凝土强度
