摘　　要：面板、趾板混凝土施工是水利水电工程大坝建设的重要环节,对混凝土坍落度的有效控制更是其重中之重。在水利水电工程大坝混凝土施工过程中,不论是面板、趾板,还是其它部位的混凝土浇筑,混凝土坍落度损失都是最常见的问题。对影响混凝土坍落度的因素进行了详细分析,提出了相应的控制措施并付诸实施,为提高混凝土浇筑质量提供了保证。Construction of concrete slab and plinth is critical to dam engineering in water conservancy and hydropower projects,and effective control of concrete slump is the top priority.During construction of dam in water conservancy and hydropower projects,slump loss is the most common scenario to be seen either in concreting of face slab,plinth,or other parts.The factors affecting concrete slump are analyzed in detail,corresponding control measures are put forward and put into practice,which provides a guarantee for improving the quality of concrete pouring.
