中文摘要：

本文应用电阻率成像法对双环入渗过程进行二维监测研究。通过在双环（内环直径25 cm,外环直径50 cm）内外以十字交叉的形式布置48个电极,获取了双环入渗过程二维剖面的视电阻率值。分析入渗过程不同深度测点视电阻率变化,得出分层饱和的时间。视电阻率成像监测双环入渗获取了水流入渗的近似形状,尤其是外环的侧向渗流,表明双环入渗促进内环的近垂向入渗。

英文摘要：

In this paper,we used the method of electrical resistivity tomography（ ERT） to monitor the double-ring infiltration in two dimensions. In order to monitor the infiltration,48 electrodes were crossed the double-ring with inner-ring diameter of 25 cm and outer-ring diameter of 50 cm to measure the resistivity. Analysis the change of resistivity and draw the picture of ERT to reveal the process of infiltration. We got the time of sand saturated in different depth. When ERT method was applied to double-ring test,it could get the shape of wetted front to some extend,especially the lateral-flow. Just for this reason,outer-ring is good for the vertical infiltration.
