| 摘 要： | 首先介绍了渗透性评价指标的测定方法。提出了一种确定室内试验渗透系与抗渗标号间关系的思路和方法，并根据在自行研制的高压多功能渗透仪上所做的大量芯样室内试验的成果，建立了江垭大坝碾压混凝土室内试验渗透系数与抗渗标号间的初步关系。最后根据江垭碾压混凝土坝芯样的室内试验成果和所收集的压水试验成果，建立了江垭大坝二级配，三级配碾压混凝土室内试验和压水试验渗透系数间的相关关系。

| Abstract: | In this paper, methods to determine the permeability evaluation index are introduced firstly, and then,idea and method to determine the relationship between indoor experimental permeability coefficient and the impermeability mark are put forward. The elementary relationship between indoor experimental permeability coefficient and the impermeability mark of RCC for Jiangya dam is established according to the results of lots of indoor experiments done by the high pressure multi_function permeameter developed by the university itself. Finally, the co_relationship equation between indoor experimental permeability coefficient and the permeability coefficient of water pressure test of Grade 2 and Grade 3 RCC for Jiangya dam are obtained according to the indoor experimental results and the water pressure test results of RCC for Jiangya dam. |
