三峡升船机船厢室段塔柱承重结构的横梁混凝土浇筑施工难度大、复杂性高、无成熟技术可供参考。本文结合三峡升船机塔柱横梁混凝土浇筑的结构特点以及施工特性，总结了三峡升船机续建工程顶部横梁混凝土的施工技术，即采用分层、分块浇筑的办法，通过科学计算后进行合理的施工机械布置和浇筑施工管理，以保证塔柱横梁混凝土的施工质量。通过对贝雷架支撑系统的监测结果分析可知，贝雷架支撑系统的应力变形、挠度变形以及排架变形均满足施工承载要求，筒体位移亦满足技术要求，贝雷架支撑系统稳定、安全。三峡升船机塔柱横梁混凝土施工实践证明了本技术方案的有效性与可靠性，亦可为类似工程的施工组织设计与现场实施工作提供一定的参考。

he concrete construction of the beam concrete of tower load-bearing structure in Three Gorges Project ship lift is difficult, with high-complexity and no mature technology available for reference. In this paper, combined with the structural features and construction characteristics of concrete pouring in tower beam of the Three Gorges Project ship lift, the concrete construction technology for continued construction of the Three Gorges Project ship lift top beam is summarized, which uses hierarchical, block pouring approaches. Through scientific computing, reasonable construction machinery layout and construction management are made out to ensure the quality of concrete construction for tower beam. The monitoring results analysis on Bailey shelf support system indicate that, the stress deformation, deflection and bent deformation of Bailey shelf support system meet the construction load requirements. The cylinder displacement also meet the technical requirements, thus Bailey shelf support system is stable and secure. The concrete construction practices of Three Gorges Project ship lift tower beam certify the effectiveness and reliability of the technical solutions. And it also provides a reference for the construction organization design and on-site implementation of similar projects.
