Abstract:Pile foundations supporting bridge abutments are often driven inside corrugated metal pipe sleeves (CMS) which extend through the approach fill to reduce downdrag or for construction expediency. The annular space between the pile and the sleeve is typically filled with uncompacted pea gravel. Designers often assume that the lateral resistance of the pile within the sleeve will be minimal; however, no test results are available to confirm this assumption. To investigate the lateral resistance of piles driven within a CMS, full-scale lateral load tests were performed. The test pile configuration included a 32.4 cm (12.75 in.) pipe pile within a 60 cm (24 in.) CMS with uncompacted pea gravel or clean sand filling the annular space. Results indicate that after small pile displacements, the lateral pile resistance was similar to that provided by an individual 12.75-in. diameter pipe pile and was even greater at larger displacements. As the pile displaced laterally, the gravel within the annular space became engaged and displaced the CMS into the compacted fill. Back-analyses indicate that the ultimate lateral pile resistance for this case can be approximated by treating the pipe-infill-CMS as a composite pile having an elastic modulus (E) and moment of inertia (I) equal to the pipe pile but with a diameter equal to the 24-inch CMS. This is the Final Summary Report #3 for pooled fund study TPF-5(272), “Evaluation of Lateral Pile Resistance Near MSE Walls at a Dedicated Wall Site.” Details of the research described in this report are available in the research final report prepared by Rollins et al. (2018) and published by the Utah Department of Transportation, along with the corresponding university thesis.
