| 摘 要： | 光照水电站大坝为目前世界上最高的全断面碾压混凝土重力坝,坝高200.5 m,坝顶总长度410 m,坝底最大宽度159.05 m,体积庞大,浇筑断面大.为了更好地对坝体混凝土进行温度控制,在坝体内全断面埋设冷却水管通水降温,冷却水管埋设与混凝土浇筑同步进行.工程施工工期紧,碾压混凝土浇筑强度大,如何有效地对坝体混凝土进行温度控制便成为一个重要的技术难题.为此,业主、设计、监理、施工四方通过研究讨论采取了一系列的温度控制措施,通过工程实践取得了良好的温控效果.

| Abstract: | The dam of Guangzhao Hydropower Station is the highest full section RCC gravity dam in the world at present.The 200.5m high dam has a 410m long dam crest,and the maximum width at its bottom is 159.05m.It has a large section to be placed as it is so big a dam.In order to exercise temperature control over dam concrete,cooling pipes are embedded for the whole section inside the dam to lower temperature through water,which is carried out simultaneously with concrete placement.Due to the tight construction sched... |
