| 摘 要： | 研究在不同的层间间隔时间条件下，采用不同的胶凝材料用量，对碾压混凝土层面分别采取不处理，铺水泥粉煤灰浆（简称水泥净浆）、水泥砂浆等处理措施对碾压混凝土层面极限拉伸值的影响。通过试验研究给出有层面碾压混凝土抗压强度、层面轴拉强度与层面极限拉伸值间相关关系。该成果针对龙滩高碾压混凝土重力坝设计的需要，为即将开工的龙滩工程提供了重要的参考依据。

| Abstract: | This paper researches the influence of no treating, paving cement and fly ash paste, and paving cement mortar on RCC layer surface upon the ultimate tensile strain of placing joint of RCC layers under the condition of different interval of placement of RCC layers and different amount of binding materials. The correlation between the compressive strength and axial tensile strength of RCC with placing joint and ultimate tensile strain of placing joint of RCC layers have been obtained. In the light of the demand of design for the high RCC gravity dam of Longtan project the research result has provided important basis and reference for the construction of Longtan project which is about to start. |
