AbstractABSTRACT: The paper presents various use of diaphragm walls for the construction of four-level junction in Warsaw. Diaphragm walls were chosen as a best solution for abutments of 2 viaducts and 1 flyover, foundations (barrettes) under 7 pillars, 60 to 100cm thick retaining walls with total length of over 570 running meters. In the paper detailed technical descriptions, geotechnical conditions, predicted theoretical horizontal and vertical displacements of walls for all mentioned diaphragm wall applications are presented. Finally, the comparison of the results of theoretical analysis and real scale monitoring results (displacements measurements and load tests) in accordance with construction stages is presented and discussed.
