摘　　要：根据CCS水电站TBM步进洞明拱段的地形条件、地质条件、结构受力情况等,按照结构力学法结合美国结构设计相关规范,在不同的荷载组合及不同的受力条件下对结构进行内力计算,得出结构不利的剪力和弯矩,进而对衬砌结构进行了配筋验算。该计算分析结果已在工程中得到应用,可为类似工程衬砌结构设计提供参考和借鉴。According to the topographical conditions,geological conditions and structural stress conditions of the open arch section of the TBM stepping tunnel of CCS Hydropower Station and according to the method of structural mechanics combined with the relevant American struc⁃tural design codes,the internal forces of the structure under different load combinations and different stress conditions were calculated,the unfavorable shear force and bending moment of the structure were obtained and then the reinforcement checking calculation of the lining struc⁃ture was carried out.The calculation and analysis results had been listed in this paper.The application in the project can provide reference for the design of lining structure in similar projects.
