摘　　要：隧道衬砌钢筋的安装质量影响衬砌结构的承载能力和稳定性,随着社会的不断发展,传统的钢筋卡具施工技术已难以满足现阶段高速铁路的质量控制要求。为解决这一问题,文章提出了一种隧道衬砌钢筋双重控制定位卡具施工技术,用于控制钢筋在施工过程中出现的偏差,提高钢筋安装施工效率,节约施工成本,为后续施工提供有力保障。The installation quality of tunnel lining steel bars affects the bearing capacity and stability of the lining structure.With the continuous development of society,the traditional steel bar fixture construction technology has been diffi cult to meet the quality control requirements of high-speed railway at this stage.In order to solve this problem,this paper proposes a dual control positioning fi xture construction technology for tunnel lining steel bars,which is used to control the deviation of steel bars in the construction process,improve the efficiency of steel bar installation and construction,save construction costs,and provide a strong guarantee for subsequent construction.
