The study involved numerical experiments using the Plaxis finite element software package. A computer calculation model of the soil-bridge system was developed. Data on the development of tangential and normal stresses during changes in the water level in the irrigation canal, transport load, and seismic impacts were obtained using a real object as an example. When analyzing tangential and normal stresses along the edge of the bridge, it was found that the presence of seismic impacts has virtually no effect on tangential stresses in the section and amounts to no more than 5 %. However, modeling an asymmetric transport load affects the value of tangential stresses by more than 40 %, which must be taken into account in numerical modeling in construction practice.
