Abstract: 
In allusion to the practical engineering of reinforced concrete shaft lining fractured in thick alluvium, based on the theoretical analyses, physical analogue tests and field measurements, by the aid of the numerical simulation calculations, the mechanical mechanism of reinforced concrete shaft lining fractured is explored thoroughly, the cracking process and dynamic laws of stress and strain inside shaft lining are obtained. The mechanical mechanism of unloading method to cure shaft lining fractured is studied. The variation laws of stress and strain inside shaft lining in every curing stage and in longer time after the shaft lining fractured being cured using the unloading method are obtained. That provides theoretical foundation and engineering parameters for preventing and curing techniques of the reinforced concrete shaft lining fractured in thick alluvium.
