Abstract: The large deformation disaster of deep underground engineering seriously affects the safety of construction and operation, so it is particularly important to analyze the influencing factors of large deformation disaster of deep underground engineering and determine the weight of each factor. Based on the understanding of catastrophe mechanism of large deformation, this paper summarizes and analyzes the influence factors of large deformation by referring to the discussion of experts and scholars. The influence factors were further divided into three first-level factors and six second-level factors, and the judgment matrix was determined by analytic hierarchy process to form the weight results of each factor. The results showed that the first-level factors accounted for the largest proportion of rock mass quality conditions, and the second-level factors accounted for the largest proportion of rock lithology conditions. The weight determination results can provide reference for engineering construction.
Key words: deep underground engineering；large deformation；analytic hierarchy process；influencing factors；weight
