The question of the possibility of using the well-known semi-empirical method for predicting settlements for underground transport tunnels of small diameter, taking into account correction factors developed for communication tunnels, is being investigated. The relationship between the ratio of the relative depth of laying and settlement of the surface and the selected ground loss volumes is considered.
