碾压混凝土层面强度特性试验研究

Experiment Study in Strength Charactersitcs of RCC Layer Surface

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 charcteristics of RCC body and RCC with layer surface has been studied under the different conditions.The results show that the compressive strength,splitting tensile strength and axial tensile strength of RCC body are all higher than that of RCC with layer surface.The dependence relations among compressive strength,splitting tensile strength and axial tensile strength of RCC with layer surface have been obtained.Aimed at the design demands of high RCC gravity dam for Longtan project that is about to start,the results of studies will provide the important reference basis.
