摘　　要：对江垭大坝二级配、三级配碾压混凝土的渗透试验和压水试验渗透系数进行了统计分析 ,并作出了各自的累积概率曲线。根据累积概率曲线得出了 6种保证率下二级配、三级配碾压混凝土渗透试验和压水试验的渗透系数值 ,并用最小二乘法拟合得出二级配、三级配碾压混凝土渗透试验和压水试验渗透系数间的关系式。拟合结果表明渗透试验和压水试验渗透系数间存在很好的线性相关关系。根据上述线性关系式 。A statistical analysis on the infiltration experiment and water pressure test for two_grade and three_grade RCC of Jiangya dam has been carried out. Their respective cumulative probability curves are also drawn. Based on these curves the infiltration coefficients for both two_grade and three_grade RCC infiltration experiment of six guarantee rates and water pressure test have been achieved, and the corelation between them is elaborated by means of least square. The result shows good linear correlation between them. In this case the coefficient of infliltration by infiltration experiment can be used to forecast that by water pressure test.
