The paper presents the procedure of introducing Eurocode 7 into the design practice in Poland. In the paper, currently used design methods have been compared with new ones, which soon will be used simultaneously with the introduction of Eurocodes. In order to enable the comparison, numerical analysis has been performed on two simple example cases presented by the committee ERTC-10 "Evaluation of Eurocode 7". This gave the authors an opportunity to assess and compare properly different design approaches - up-to-date and new, now being introduced. Final conclusions and issues giving rise to further discussion have been presented at the end of the paper. [ABSTRACT FROM AUTHOR]

Due to the influence of the engineering works on buildings in the vicinity of deep excavations, two large Warsaw underground stations were constantly monitored. The results of measurements of the displacements of diaphragm walls are presented. Assessment of displacements was carried out on the basis of high-precision land surveying of fixed points positioned on diaphragm walls. The conclusions concerning maximum horizontal displacement of diaphragm walls as well as evaluation of real value of soils parameters based on the results of measurements have been presented.
