摘　　要：在秦岭腹地南北气候分界线区域确定大坝建设中变态混凝土配合比,以往研究经验较少。本文通过三河口水利枢纽碾压混凝土大坝中变态混凝土的试验研究,总结了该特殊地区碾压混凝土大坝中变态混凝土配合比设计经验,可对引汉济渭工程建设中黄金峡碾压混凝土坝体的变态混凝土配合比试验研究起到参考作用,也为变态混凝土施工方案在秦岭南北气候分界线区域的推广奠定了基础。在三河口碾压混凝土大坝施工中该变态混凝土配合比试验成果已得到成功应用,其物理、化学性能及各强度等级等指标均满足设计和规范要求。There is little experience in determining the mix ratio of distorted concrete in dam construction in the north-south climate boundary area of Qinling Hinterland. The design experience of the distorted concrete mix ratio in the RCC dam of the special area is summarized, which can be used as a reference for the experimental study of the distorted concrete mix ratio in Huangjinxia RCC dam in the construction of the Hanjiang-Weihe River Diversion Project based on the experimental study of the distorted concrete in the RCC dam of Sanhekou Hydropower Project. It also laid a foundation for the extension of the distorted concrete construction scheme in the climate dividing line area of the north and south of Qinling Mountains. The test results of the distorted concrete mix ratio have been successfully applied in the construction of Sanhekou RCC dam. Its physical and chemical properties as well as strength grades meet the design and specification requirements.
