This contribution gives a case study on the deformations of anchor back-tied steel sheet pile walls and retained soils at deep excavations in soft soils overlying bedrock in Stockholm. Instrumentation results show the deformation of the retained soils is larger than that from similar case histories. The monitored anchor stresses increase quickly in the early stages of excavation and decease gradually to a constant value during later stages, while the lateral displacements of the sheet pile walls increase gradually. The results of both monitoring and numerical analysis show that this dynamic feature becomes weak as the thickness of the underlying soils is small. The decrease of the anchor stresses is mainly due to the flectional behavior of the sheet pile wall and the stress rotation in the retained soils.
