摘要
三峡工程泄洪坝段是三峡大坝坝体最高、受力最大、结构复杂、技术要求最高的重要建筑物之一 ,由于受各种因素的影响 ,坝体基础约束区混凝土在高温季节持续浇筑 ,通过设计、施工采取一系列综合措施后 ,克服了高强度、大方量约束区混凝土在高温季节浇筑的温度控制难题 ,保证了混凝土的质量和进度。
The spillway is one of the important structures for the Three Gorges project,with the highest blocks,bearing the max.water pressure,complex geometry and strict technical requirements.Due to various factors,the concrete in the foundation restraint area must be placed continuously in hot weather.The tough problem with the temperature control.over concreting in the foundation restraint area with higher placment rates and high volume,has been offset by a series of integrated measures proposed by the designer an...
