The spatial distribution of fractures near the site was characterized through results of outcrop investigations and in-situ hydrogeological tests. The hydraulic conductivity of dominant fracture sets are determined and the hydraulic conductivity tensor is obtained accordingly. Based on the results of fracture characterization and associated parameters determined, this study adopts the software embedded in the Groundwater Modelling System (GMS) to establish a three-dimensional anisotropic numerical model to simulate flow of ground water. In comparison with cross-hole pumping test, the numerical model is utilized to investigate the effect of fractures induced anisotropy on groundwater flow. Studies show that when the principal permeability direction is rotated 10 degrees clockwise with respect to Y-axis, both horizontal and vertical flow increase at a rate of 1.52 times. ? 2017 by Korean Society for Rock Mechanics. |
