摘　　要：通过渗透张量原理对断层影响带围岩的主渗透系数及渗透主方向进行了计算,并对隧道走向和渗透主方向的关系进行了分析;利用地下水动力学法对断层影响带的涌水量进行了预测;利用断裂优势指标及其量化评价体系对各个断层带的突水优势进行了评价。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.
