| Abstract: | In this paper,for the case of creeping of surrounding rock of shaft, the law of stress anddisplacement changing with time in the shaft lining was analysed with theory of rock creep, and the timedependent failure criterion of shaft lining was established. The research is significant for supportting designof shaft and the stress in the lining and its stability prediction at different periods. |
