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 )、水泥砂浆等措施对碾压混凝土层面抗渗性能的影响。通过研究碾压混凝土层面抗渗性能及碾压混凝土本体抗渗性能 ,给出不同工况碾压混凝土层面相对渗透系数关系。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 effects of different cementitious materials dosage, different treatment of roller compacted concrete layer, laying of cement fly ash (referred to as cement paste) and cement mortar on the performance of roller compacted concrete Impermeability. By studying the impermeability of roller compacted concrete and the impermeability of roller compacted concrete, the relative permeability coefficient of roller compacted concrete under different conditions is given. 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.
