Abstract
This study aims to conduct an in-depth exploration of temperature control techniques for dam concrete in hydropower and water conservancy project.By analyzing the key points of temperature control techniques during the pre-construction,construction,and post-construction stages of dam concrete,and combining case studies from multiple domestic and international hydropower projects,this paper statistically compares temperature control measures for different dam types.The research reveals that:The concrete mix design primarily adopts a system of"moderate/low-heat cement+Grade I fly ash+retarding water-reducing agent";The required pouring temperature and internal temperature for conventional concrete dam types are higher than those for roller-compacted concrete(RCC dam types;During the cooling water circulation process,initial-stage water cooling controls the maximum concrete temperature,mid-stage water cooling manages the internal-external temperature difference,and a"synchronized cooling zone"is established to reduce interlayer temperature differences between upper and lower layers.These technical measures provide valuable references for engineering technicians,aiding in the implementation of effective temperature control practices in actual projects to ensure dam concrete quality and guarantee the safe and stable operation of hydropower and water conservancy projects.关键词
