摘要
万家口子水电站工程拦河大坝为薄壁型碾压混凝土双曲高拱坝,针对坝址固有的气候特征,以及碾压混凝土因单位体积混凝土的胶凝材料含量偏少而抗裂性能较差的特点,施工过程采取多种有效的施工温控技术措施,最大限度地避免坝体出现温度裂缝,保证了双曲拱坝工程质量。
The dam of Wanjiakouzi Hydropower Station is a thin-walled RCC double curvature high arch dam.In view of the inherent climate characteristics of the dam site and the poor crack resistance performance of RCC due to the low content of cementitious materials per unit volume of concrete,a variety of effective construction temperature control technical measures are taken in the construction process to avoid temperature cracks in the dam body to the greatest extent and ensure double curvature quality of double curvature arch dam project.
