In order to explore the negative impact of tunnel construction on the groundwater environment, a negative effect evaluation system of tunnel groundwater was constructed according to the relevant specifications and references with the consideration of the complexity and uncertainty of groundwater environment. Firstly, the evaluation index system of negative effect of tunnel groundwater was established based on the pressure-state-response (PSR) model and the idea of whole process management. Then, the combined weight of each evaluation index was determined using analytic hierarchy process (AHP) and intuitive fuzzy entropy (IFE), and the coupling model of improved intuitionistic fuzzy set and technique for order preference by similarity to an ideal solution (TOPSIS) was established to calculate the negative effect level of tunnel groundwater. Finally, the evaluation model was verified with an engineering case. Compared with the evaluation results of different models in literature, the reliability and superiority of the model were verified.
