Attention is mainly paid to the development of a method for predicting deformations of the earth surface caused by building subway stations, based on numerical modeling. The issues of developing numerical models of complex spatial underground structures have been considered, with regard to the construction sequence. A geomechanical model of predicting deformations in construction of underground structures in claystone-like clays, described as a non-linear transversely isotropic medium, has been proposed. Detailed analysis of the results of the monitoring of the earth surface settlement has been made in the construction of the “Obvodny Kanal” subway station in St. Petersburg (Russia). For the construction of the "Obvodny Kanal" subway station, calculation was made in order to determine the deformation of the earth surface. Substantiation of the reliability of the proposed method of predicting deformations of the earth surface is made based on comparing the monitoring results to a numerical simulation. https://www.biotech-asia.org/vol12no3/estimation-of-surface-settlements-troughs-due-to-subway-station-construction-in-claystone/ deformation; stresses; subsidence of the earth's surface; geomechanical model; subway station; claystone; stiff clay
