摘　　要：三峡地下电站引水隧洞上弯段属高速高压水流区,衬砌混凝土质量要求高,空间结构特殊,施工难度大,所提出的双曲无轨滑模具有空间双曲结构特点,特设可旋转修补抹面平台,实现无轨滑升,无须接缝和混凝土衬砌表面处理,提高了施工质量,加快了施工进度,节约了成本,具有良好的经济效益,对同类型的工程施工技术提供了重要的参考价值。The concrete lining for the upper bend section of diversion tunnel in the Three Gorges underground power station is required with high quality as the high-speed high-pressure flow and the special spatial structure.A hyperbolic trackless sliding formwork is designed for the construction of concrete lining.The slip formwork equips with rotated repairing trowel finish platform and can slip and lift without track.The application of this slip formwork can eliminate joint and lining surface treatment,improve construction quality,speed up construction progress and save cost.
