Field experiments with laterally-loaded pile groups have been conducted in a very soft clay at Harvey, Louisiana.Six series of loadings were performed; both static and cyclic tests were done with five-and ten-pile circular groups of six-inch diameter pipe piles, and corresponding single-pile tests were performed for comparison. Deflections were enforced at two elevations by a special loading device to simulate pile-head restraints typical of offshore structures. The measurements taken to record the behavior of the piles throughout the history of loading included total load and deflection of the group, plus individual pile shears and bending moments. Center-tocenter spacing in the 5-pile groups was 3.4 pile diameters and 1.8 diameters in the 10-pile group.
