| Description | The paper presents a case study of a deep, extensive excavation executed in the downtown of Warsaw in a very close proximity to the existing railway tunnel. The tunnel, containing 10 railway tracks, is located at the outlet from the main Warsaw railway station. The construction of the excavation may affect the track geometry and cause track settlement or heave depending on the stage of construction. Prior to the construction, the numerical 2D FEM analysis were performed in order to evaluate the impact of the excavation to the railway tunnel. After the project implementation, a comparative analysis of the results of numerical analyzes and measurements of vertical displacements of railway tracks carried out during construction was performed. It occurred that the theoretical displacements of the rail obtained in the analysis were underestimated. A discussion of numerical analysis in relation to measurement results is presented.
