| 摘 要： | 现场压水试验的碾压混凝土渗流常处于非恒定状态，压水试验规程中按恒定流确定渗透系数的方法不再适用.本文仿照混凝土试件快速试验确定渗透系数的方法，推导出压水试验过程中渗流处于非恒定状态条件下碾压混凝土求渗透系数的方法和公式.该方法曾应用于江垭工程现场压水试验，较为真实的反映了碾压混凝土的渗透特性.

| Abstract: | The conventional method for determination of permeability coefficient of RCC is not applicable to the testing conducted in-site, since the seepage in RCC is always unsteady in this case. Following the existing quick testing method for permeability of concrete speciment, the calculation formula for determination of permeability coefficient of RCC under the condition of unsteady seepage flow is deduced. The applicability of this method is verified by the water pressure test in Jiangya Project. |

| Keywords: | RCC permeability coefficient water pressure test unsteady seepage |
