摘　　要：提要万家寨水利枢纽采用低热微膨胀混凝土筑坝技术研究是水利部重点科技项目。使用该项技术可以加大仓面，减少纵缝，简化温控措施，达到加快施工进度、降低工程造价的目的。本课题研究历经三年已取得成果，在工程施工中结合缆机基础、纵向围堰及尾水挡墙混凝土浇筑，进行了现场试验，亦获得预期效果。Abstract Application and study on the concrete of low heat and micro expansion cement in Wanjiazhai Water Control Project is an important item of the Ministry of Water Resources.Application of the technology can enlarge the area of concrete block in its placement, reduce the longitudinal joints, and simplify the temperature control methods,further more,speed up the constructon process and diminish the project cost.The project has been carried for three years and successfully. During the construction of the foundation of the transporter cableway,the longitudinal cofferdam,and the tailwater wall,tests in the field had been done and achieved expected results.
