Abstract：
In order to gain essential detailed data for future selection of TBM type, to research the adaptability of a
TBM used in urban subway tunnels, and to implement the transition from quantitative adaptability analysis to qualitative and quantitative adaptability analysis, the TBM test section of Chongqing Rail Transit line 6 phase I is used as an example to explore TBM adaptability assessment criteria based on the evaluation index system which is built by a comprehensive contrastive analysis of influencing factors of the adaptability assessment, with the scores and weights of numerous evaluation indexes determined by the analytic hierarchy process and the engineering analogy method. The adaptability of the TBM used in the urban subway was synthetically evaluated by the final assessment criteria. The conclusion and suggestions are as follows: 1) the adaptability of the TBM used in this project is evaluated as A-excellent; 2) the adaptability evaluation index system of the TBM method should be adjusted regarding different projects; 3) further in-depth study should be performed for the scores of the TBM adaptability evaluation index; and 4) with the update of engineering information, the adaptability assessment criteria should be revised and improved correspondingly.
