Abstract: Combined with engineering cases, the mechanism of inrush through fault which is water-inconductive in initial geological condition, has been studied. It is found that the fault zone can act as a barrier of excavating-induced stress & deformation under some conditions. The barrier effect may cause intense deformation, high deformation gradient in rockmass within the fault zone, more intense deformation and stress concentration between the excavated space and the fault. All of them may easily arouse rockmass deformation and geological structure slip within and near the fault zone, and furthermore lead to groundwater inrush. The rationality of analyses mentioned above has been confirmed by the specific engineering cases.

Key words: groundwater inrush, fault, barrier effect, stability controlling, inrush controlling
