A new hesitant fuzzy 2-tuple-data envelopment analysis (DEA) model was established in order to assess the risk of land subsidence along high-speed railway. Assessment opinions were handled with the computation theory of hesitant fuzzy 2-tuple linguistic model. Experts’ weights were adjusted based on the principle of maximum group consensus; and the factors’ weights were determined by using the DEA model; which made up for the defects of the previous assessment methods; such as difficulty of passing consistency test; difficulty of assessment process; and low degree of consensus of the evaluators. The hesitant fuzzy 2-tuple-DEA analysis model was applied to a high-speed railway project under construction in Huaibei; Anhui Province. The risk assessment index system of hazard factors; vulnerability factors and sensitivity factors was established. The fuzzy assessment set of individual hesitation and matrix of group hesitation were established; and weight of each factor was obtained. The visual display of risk distribution in the disaster; vulnerability and sensitivity index assessment area was realized based on GIS system. Land subsidence risk distribution along the high-speed railway was obtained. Results show that DK66-DK67 is the highest risk section; and the subsidence monitoring in this section should be strengthened. © 2024 Zhejiang University. All rights reserved;
