CCS电站输水隧洞TBM管片结构设计与生产.

In this paper, the design and production process of TBM segment of the water tunnel of CCS Hydro-Junction Project were summarized. Firstly, according to the engineering geological conditions, the segment selection was made considering the diameter of the tunnel, the stress characteristics and the construction difficulty. Then, referring to the modified routine method recommended by the American code, the structural stress analysis and reinforcement calculation of the segment were carried out by the finite element analysis software ANSYS. Finally, according to the various technologies of concrete casting and maintenance process, the technical requirements for the whole process of segment production and the technical standards for factory acceptance were formulated. The design and production process of TBM segment in CCS water control project were summarized by the paper, the mechanical characteristics of segment structure were defined, some technical standards such as raw material inspection, concrete preparation, concrete vibration, concrete maintenance and factory inspection of segment concrete were summarized.
