摘要

Last year a deep excavation for the construction of a metro station in Warsaw was executed in complex geotechnical conditions. In the first stage of the investment process the primary soil investigation was performed. Basing on the results of this investigation calculations of supporting system and the design of casing were carried out. In the subsequent investment stages complementary soil investigations were performed and the results were taken into account in the final analysis, design and dimensioning. Significant differences were observed in the results of analysis made at each investment stage. In the paper, description of the case and multiple numerical analysis of the case with variation of soil parameters are presented. The discussion of calculation results in relation to the changing geotechnical data is presented. At the end comparison of theoretical displacements and the displacements of the wall measured on site is given and final conclusions are provided.
