大朝山水电站碾压混凝土施工特点

The features of rolled concrete work construction of Dachaoshan Hydropower Station

介绍了碾压混凝土施工优点，云南大朝山水电站工程概况，大坝标段全断面碾压混凝土重力坝施工情况以及该工程PT双掺料替代粉煤灰掺和料，变态混凝土施工，大仓斜层碾压混凝土施工，施工中V，值的控制，高温差下的混凝土温控等施工特点。

The advantages of rolled concrete work constructi on , the general situation of Dachaoshan Hydropower Station, and the construction o f the rolled concrete gravity dam, are introduced. The features of construction concerning with the use of PT instead of fly ash, distorted concrete constructio n, and the rolled concrete work construction in large silo with dip sections, V c value control in construction, and the construction with large temperat ure difference are also demonstrated in the paper.
