摘要:针对小湾水电站坝后水垫塘抗冲耐磨混凝土施工,工程量大,设计标号高,水胶比小,外掺材料多,跨高温、雨季,且抗冲耐磨混凝土粘稠性强,易发干发白、产生干缩裂缝,混凝土振捣困难,抹面平整度难以控制等特点,提出了混凝土配合比优化设计,混凝土拌和,过流面表面不平整处理,早期塑性干缩预防,后期收缩裂缝、温度裂缝预防,雨季施工防雨等措施,保证了施工质量和进度,取得了良好的社会经济效益。%Some difficulties has been encountered in the scour resistant concrete construction of water cushion pool in Xiaowan Hydropower Station: large construction quantity with high design grade , small ratio of water and gel , many mixed materials, high-temperature rainy season , thick abrasion-resistant concrete easy to dry and white which leads to dry shrinkage crack , difficult concrete vibrator and uneven surface .Measures such as optimization design , concrete mix-ing, flow surface roughness treatment , plastic shrinkage prevention in early stage , shrinking and temperature cracks pre-vention in later stage , rain proof in rainy season are proposed in order to ensure construction quality and progress and to achieve good social and economic benefits .
