深溪沟水电站厂房坝段温控方案研究

Study of Temperature Control Measures of Powerhouse Dam Section for Shenxigou Hydropower Station

针对深溪沟电站的环境条件和施工特点,按照理论分析-数值仿真-经验判断的技术路线,结合深溪沟厂坝段的实际体形和材料参数,展开了各个坝段的混凝土施工期全过程仿真分析研究,对影响混凝土温度与应力的主要温控措施进行了敏感性分析,提出了符合深溪沟电站厂房坝段工程实际的温控防裂措施,也为类似工程提供参考.

In consideration of environmental conditions and construction features at Shenxigou Hydropower Station, combined with the actual dam shape and material parameters of Shenxigou Powerhouse dam section, the full-process simulation analysis was performed for various dam sections in concrete construction period, and the sensitivity analysis is made for main temperature control measures affecting concrete temperature stress by the technique route of theoretical analysis-numerical simulation-empirical judgment. Finally the temperature control requirements and anti-crack measures that tally with the actual conditions of Shenxigou Hydropower Station are put forward, so as to provide a reference for similar projects
