Abstract  The method of shotcrete for roadway and shaft support has been developedin no less than fifty underground metal mines in China, but so far a theoreticalanalysis is lacking. Since the deformation on the support and that on the contact plane of rockmass are identical and at the same time taking into account the reaction of rockmass on support, the correlation of stress-strain and displacement of rock mass inroadway and shaft of circular cross-section under condition of plane strain vary-ing with time may be viewed on a rheological model of rock mass. Hence, thecorresponding expression for the distribution of stress and strain over the rockmass and the equation for calculating stress-strain and displacement of shotcretesupport are worked out. The formulae of thickness and strength in various desi-gnings required for shotcrete thus obtained are reliable for engineering practice.
