Abstract: The Berliner wall with 1 level of ground anchors was designed to ensure the excavation stability. A 8 to 9 m deep excavation was carried out for residential building on the street Przy Bażantarni in Warsaw. The ground has been identified homogeneous ground conditions occur mainly cohesive soils with a very high shear strength. The loads in the 3 ground anchors were measured throughout the period of their work in the construction. Back analysis was performed to determine the soil parameters reflecting the work of retaining structure. For the purposes of the analysis laboratory triaxial tests was conducted with drainage of water from the pores of the soil (TXCID) on samples taken when digging the trench. Calculations were made using the construction module of ground reaction. The calculation results are compared with the measurement results. Based on the results of the analyzes and the results of the measurement of forces in anchor made recommendations regarding the selection of parameters for the design of retaining structures similar ground conditions.
