摘　　要：普定碾压混凝土拱坝依靠碾压混凝土自身防渗，对施工期的温度控制防裂有较高要求。结合国家"八五"科技攻关，通过混凝土配合比优化、合理选择施工时段、充分利用层间间歇散的热等措施，获得了良好的温度控制效果，顺利建成了目前世界最高、中国首座碾压混凝土拱坝。Tantiseepagc of Puding RCC arch dam is depend on its RCC body, and the temperature control during during construction periodwas key crack stopper. We adopted are useful measures such as optimizing concrete ed proportion, selecting proper constructionduration, fully using the construction intervals between two layers for heat elimination and etc. The temperature effect was prettygood.

关 键 词：碾压混凝土拱坝 温度控制 防裂
