摘　　要：龙滩水电站大坝是目前世界上在建最高的碾压混凝土大坝。如何控制全断面碾压混凝土坝体温度是关系大坝运行安全的关键。而龙滩大坝碾压混凝土施工仓面大,用水量大,与常态混凝土大坝通水冷却略有不同。结合龙滩工程实际,采取了不同的布置方案进行通水冷却施工,满足了坝体温度控制的要求,为同类工程积累了经验。Longtan Dam is the highest RCC dam under construction in the world at present.Temperature control for entire placement section of the RCC dam body is essential for safe operation of the dam.Comparing with conventional dam,Longtan RCC dam was constructed with large placement section and large water demand,therefore,water cooling system for dam body is somewhat different.Considering real situation of Longtan project,different layouts were taken to carry out water cooling system construction to meet requirements of dam temperature control and provide experiences for the similar projects.
