Abstract [en]

The apparent earth pressures measured at the South Link Project in Stockholm are used to analyze the pressure on sheet pile walls at deep excavations in soft soils overlying bedrock. The depths of the excavations vary from 3 m to 16 m and the toes of the walls are keyed into bedrock. Measured apparent earth pressures are over the Peck's (1969) envelope for soft clay but approximate to initial stress at rest. The normalized distribution pattern of the pressures indicates a large apparent earth pressure in the upper part of a test section. The well kept anchor load contributes to the large apparent earth pressure. This case indicates that the beneficial effect of the presence of bedrock may be over-shadowed by the low strength of soft soils, especially when the distance from excavation level to bedrock is larger than the depth of excavation.
