Risk Assessment of Water Inrush in Tunnel through Water-Rich Fault
Abstract A fuzzy comprehensive evaluation method based on gray theory is proposed to assess the risk of water inrush in tunnels through water-rich fault. The Grey-Fuzzy method consists of two parts: one is the single factor evaluation matrix which is created by evaluation index and the risk grade membership function, the other one is the weight of each evaluation index set by using the norm gray correlation degree. Five influence factors (fault dip, groundwater level, RMR, permeability and strata inclination) are selected as evaluation indices from the aspects of stratum lithology, geological structure and hydrogeological condition. The orthogonal numerical simulation test is applied to obtain the quantitative evaluation index of geological structure. Finally, the established risk evaluation method of water inrush was applied to the water diversion tunnel project of Longjinxi. The evaluation results can match the reality situation in tunnel construction.
