Increased Lateral Resistance of Pile Group in Clay Using Compacted Fill
The lateral resistance of pile groups in soft clay is typically relatively low. Rather than drive additional piles, some have suggested that lateral resistance could be increased by replacing the top 5 to 10 pile diameters with compacted granular material. To evaluate this possibility, lateral load tests were first performed on a full-scale pile group in clay. The pile group consisted of 15 steel pipe piles with an outside diameter of 324 mm driven in a 3 x 5 arrangement. A second test was then performed after 0.9 m of clay was excavated and sand was added to produce a 2.4 m layer of compacted sand. This relatively simple approach increased the lateral resistance by about 30% or 450 kN at a displacement 70 mm. The cost effectiveness of this approach increases as the undrained shear strength of the clay decreases and the friction angle of the compacted sand increases.
