| Abstract: | The main permeability coefficient and penetration direction of wall rock in fault affected zone are calculated through permeability tensor theory and the relationship between tunnel direction and main penetration direction is also analyzed.Gushing water in fault affected zone is predicted using underground water dynamics method.The advantages of water inrush in each fault zone are evaluated using fracture advantage indicator and quantitative evaluation system. |
