研究不同工况有层面碾压混凝土及其碾压混凝土本体强度特性 ,得出碾压混凝土本体抗压强度、劈拉强度和轴拉强度均大于有层面碾压混凝土的相应强度。试验给出有层面碾压混凝土抗压强度、层面劈拉强度、层面轴拉强度间相关关系。研究工作针对龙滩高碾压混凝土重力坝设计的需要 ,其成果为即将开工的龙滩工程建设提供了重要的参考依据。
The strength characteristics of roller compacted concrete and roller compacted concrete under different working conditions are studied. It is concluded that the compressive strength, splitting tensile strength and axial tensile strength of roller compacted concrete are greater than the corresponding strength of roller compacted concrete. The experimental results show the correlation between the compressive strength of RCC, the splitting tensile strength and the axial tensile strength. The research work is aimed at the design of Longtan high RCC gravity dam. The results provide an important reference for the construction of Longtan project.
