三峡升船机塔柱结构复杂，属于高层薄壁结构，混凝土温度受环境温度影响较大，其混凝土温控难度极大。在施工实践中，通过优化混凝土配合比、合理布置混凝土冷却系统、科学调控冷却水温度与通水时间，科学调整外部环境温度、同时引进混凝土养护新材料、新工艺，并且加强对温控的施工管理等措施，保证了塔柱混凝土的施工质量，证明了温控方案的科学合理性。三峡升船机塔柱混凝土温控防裂技术对研究国内外升船机工程温控措施技术水平，提高水电工程混凝土施工质量，节省工程造价等具有重要的参考价值。

The structure of ship lift tower in Three Gorges Project, belonging to high-rise and thin-walled structure, is complex. And its concrete temperature is greatly influenced by the ambient temperature. Thus, the concrete temperature control of it is extremely difficult. In construction practice, by optimizing the concrete mix, rationally arranging the concrete cooling system, scientifically regulating the temperature and time of cooling water, scientifically adjusting the external ambient temperature, introducing new materials and new processes of concrete curing and strengthening the construction management measures of temperature control and other measures at the same time, the construction quality of concrete tower is ensured and the scientific rationality of the temperature control program is proved. Temperature control and crack prevention technology for concrete in ship lift tower of Three Gorges Project has important reference value to research the technical level of temperature control measures for ship lift projects at home and abroad, to improve the quality of concrete construction in hydropower projects and to save the cost.
