| 摘 要： | 本文对江垭大坝二级配、三级配碾压混凝土的室内试验和压水试验渗透系数值进行了统计分析,并作出了各自的积累概率曲线。根据累积概率曲线得出了6种保证率下二级配、三级配碾压混凝土室内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、三级配碾压混凝土室内试验和压水试验渗透系数间的线性关系式。拟合结果表明室内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,可利用室内试验渗透系数来预测压水试验渗透系数。

| Abstract: | The permeability coefficients for two-grade and three-grade aggregate RCC of indoor experiment and from water pressure test in situ are statistically analyzed. According to the accumulated probability curve the permeability coefficients with 6 kinds of guarantee rate both for indoor experiment andtest in situ are derived and linear relationship is found by using least squaremethod. On the basis of this linear relationship, the coefficient from water pressure test can be predicted according to the experment. |

| Keywords: | RCC indoor experiment water pressure test premeability linear correelation |
