SOIL DEFORMATIONS NEAR ANCHORED SHEET PILE WALLS

Bransby & Milligan (1975) showed how the deformations in the soil behind a flexible cantilever retaining wall could be predicted using a simple velocity field. For a wall with an anchor or support near the top the simple velocity field cannot in general apply. The deformations behind such a wall were therefore studied experimentally using model walls and measuring displacements in the soil by the radiographic method. The pattern of displacements was found to be much more complex than for the cantilever walls, but could be divided into a number of relatively simple zones, related to the deformation of the wall, linked by a more complex zone in which arching occurred. For the case in which the soil is deforming without change of volume the simple velocity field could apply whatever the mode of deformation of the wall. Results of measurements made on full-scale walls in the field show good agreement between observed short-term displacements in soft clay and those predicted by the simple velocity field from the deformations of the wall.
