摘要
对大坝碾压混凝土抗渗、抗冻和抗裂的评估指标进行分析研究,建议抗渗指标以渗透系数给出,可用含气量的多少来评估抗冻性,建立的抗裂模型和简单抗裂模型可用于对大坝混凝土配合比有关参数的优化.
This paper researches the index for estimate on the impermeability,frost resistance and cracking resistance of dam RCC,and proposes the coefficient of permeability qua the impermeability index,the quantity of gas qua the index of frost resistance.The model of cracking resistance and simple model of cracking resistance established can be used in the optimizing proportion of dam concrete mix.
