Abstract:According to the properties of influences of geoelectric field on solution seepage,a model of electro-dynamic seepage has been established;and the influences have been investigated through experiments. The results indicate that it is obvious that the geoelectric field affects the seepage properties;and the electro-dynamic seepage properties are affected by factors such as the intensity of geoelectric field,the permeability of rock mass,the characters of leaching solution and so on. Under the same pressure gradient,the seepage velocity of leaching solution well increases with the intensity of positive electric field,and decreases with the negative electric field. The seepage diffusibility of leaching solution and its wetting ability to fractured rock mass can be enhanced or weakened by the electric field.
