Abstract:

Based on the saturated and unsaturated seepage theory, a numerical simulation on the seepage field in an anisotropic complex geological body was done. A mine which had a  typical fold shape geological structure in Fuxin was taken as research background, a three-dimensional geological model was built using the Kriging interpolation method, and then the pressure gradient changes in the geological body  were simulated and analyzed, when the principal direction of hydraulic conductivity and global coordinate system were of different angles. The results showed that the pressure gradient  reached  the maximum at 90°. The type  of geological structure and formation were  the key factors of the direction and density of the pressure gradient.

Key words: hydraulic conductivity, anisotropy, complex geological body, Kriging, pressure gradient
