Shaft lining thickness change constructions is common in shaft construction process where shaft lining fracture will increase. By implementing monitoring at shaft lining thickness variation regional, contrastive analysis based on the measured data, it is revealed that the stress fracture is associated with the ways of shaft lining thickness change. Compared with the gradual type construction method, the shaft lining stress concentration regional significantly become large and there is greater influence on shaft lining fracture when the abrupt type construction is used in the process of the shaft lining thickness change constructions.
