Evaluation of Lateral Pile Resistance Near MSE Walls at a Dedicated Wall Site - Phase 2
The Phase 1 study included construction of a dedicated mechanically stabilized earth (MSE) wall site in Utah with instrumented piles behind the 20-ft high wall. This wall site will be reused for the Phase 2 testing. Funded tasks for this Phase 2 study include: 1. Excavate the top 6 ft of the soil backfill behind the existing MSE wall. 2. Instrument MSE reinforcements and piles with strain gauges. 3. Re-compact the top 6 ft of the soil backfill behind the existing MSE wall. 4. Conduct cyclic lateral pile load testing. 5. Conduct fixed-head lateral pile load testing. 6. Conduct lateral pile load testing of larger-diameter piles (24-inch diameter), to be newly placed between cut-off existing piles. 7. Conduct lateral pile load testing of a pile group. 8. Develop p-multipliers for Phase 2 lateral pile load testing results, compare these with the Phase 1 results, and update the overall p-multiplier equation as necessary. 9. Develop tensile force equations for Phase 2 lateral pile load testing results, compare these with the Phase 1 results, and update the overall tensile force equations as necessary. 10. Submit a final report that documents the Phase 2 research effort. 11. Report results to TAC committee members in video conferences. 12. Make presentations at American Association of State Highway and Transportation Officials (AASHTO) bridge engineers’ committee meetings and Transportation Research Board (TRB) events to aid in national efforts to implement the study results.
