The purpose of the study was to confirm the capability of numerical simulation of soils shift and bridge structures elements deformations during underground construction. The main goal of this simulation was to assess the harmful effects of mining operations on the existing bridge load-bearing elements. Modeling of bridge structures undermining by earth pressure balance tunneling boring machines (EPB TBMs) was carried out both at the design stage for predicting deformations and at the stage of
