| 摘 要： | 天花板水电站大坝为碾压混凝土双曲拱坝,坝体受水平建基面及两岸基岩约束作用较强,加之高温季节浇筑强约束区混凝土,增大了温控难度.大坝施工过程中采取的主要温控措施之一是在坝体内埋设冷却水管进行分期冷却,冷却水管分部位并按结构分区布置.实践表明,天花板大坝的冷却水管布置及通水冷却方案可以有效控制混凝土温升,冷却效果良好.

| Abstract: | Because the Tianhuaban RCC Arch Dam bears stronger restraints imposed by the rocks in dam foundation and two banks,and the concrete in strong-restrained zones will be poured in hot season,the temperature control is important.One of temperature control measures is laying water cooling pipes in dam body to cool the concrete with phased manner.The pipes are arranged in different zones according to the position and dam structure.The practice shows that the layout of water cooling pipe and the cooling programs c... |
