Experiment-5: Backfill Test #3: 3-ft Wide Gravel Zone with Loosely Compacted Sand and Later with No Backfill
Experiment Type: Field
Description: Tests were done to assess the lateral load response of full-scale pile cap with a backfill condition of 3-ft wide gravel zone with loosely compacted sand. Also, a test with no backfill in place was done. The test site had three basic features: a reaction foundation, a test pile cap, and the backfill soil zone. The pile caps were subjected to static, cyclic and dynamic loadings. The hydraulic load actuators statically loaded (pushed slowly) the pile cap to target displacement levels that were incrementally larger. For each level, the actuators would apply low frequency, small displacement loading cycles to the pile cap, and an eccentric mass shaker would apply higher frequency, small displacement dynamic load cycles.

The general testing procedure was followed, except for a breakdown of the shaker before the last two displacement levels.
