Abstract: Soft rock under high stress is prone to occur large deformation, and jamming disasters often encounter when TBM passes through such stratum. Currently, there is no classification standard that can directly guide TBM construction adaptability for large-deformed surrounding rocks. Analyzing the advancing state of TBM, the deformation of surrounding rock and the pressure on the shield were regarded as the main indexes. The contact state of the surrounding rock and TBM was distinguished according to the relationship between the rock deformation and overcut size; and the state of shield stress was distinguished according to the relationship between the shield friction and TBM ultimate thrust. Moreover, considering the accessibility and universality of surrounding rock classification, the classification standard of TBM construction adaptability for large deformation surrounding rock was established according to the potential jam status of TBM. The classification standard was applied to a specific project to verify its reasonability. The results showed that the TBM construction adaptability classification for large-deformed surrounding rock required taking rock deformation and shield stress into consideration comprehensively. The proposed standard could guide projects directly and effectively to avoid jamming disasters.
