The article deals with the problem of ensuring the stability of grillages and pile foundations used to hold shaft sinking systems during the construction of vertical subway shafts. The features of such foundations’ operation in the process of shaft sinking are investigated, in contrast to similar structures that receive pressure from a building under construction. The importance of taking into account the mutual influence of shaft sinking and pile foundations of the shaft sinking systems’ supporting structures is shown. The design of bored piles and the technological scheme of mortar injection are proposed, which provide a change in the operating mode of pile foundations and regulation of its bearing capacity.
