The construction monitoring of Ráckóczi square metro station of Budapest Metro Line 4 offered a great opportunity to back analyse the braced deep excavation in the building period. Building movements, strut forces and wall displacement measurements have been compared to numerical results derived by PLAXIS using HSsmall soil model. Considering the influence of small strain stiffness of plastic soils, good fit of the measured and calculated movements could be observed and the strut forces could be calculated reasonable. Curve characteristic of surface settlements was explored, as well. Analysis were carried out to observe influence of the following inputs on the numerical results: soil material model; consolidation effects, boundary conditions. A detailed evaluation is given about the results of parametric analysis.
