Abstract：This paper deals with the effect on infiltration process of clay interlayer in sand by lab experiments on water infiltration into sand column that contains a clay interlayer.By analyzing experiment data,a conclusion is drawn that the effect is infiltration reduction,which can be explained as following: clay interlayer converts the non-linear process in sand into linear process of infiltration in clay interlayer.This results in the infiltration process of clay layer to be a stable infiltration stage with a smaller infiltration rate and a slower advance speed of wetting front.
