Comprehensive Field Load Test and Geotechnical Investigation Program for Development of LRFD Recommendations of Driven Piles on Intermediate GeoMaterials

The overall goal of the proposed research project is to develop load and resistance factor design (LRFD) recommendations for driven piles on intermediate geomaterial (IGM). Recognizing the design and construction challenges of piles driven on IGM, the research project is proposed to accomplish the following objectives: (1) Determine representative engineering properties of soil and IGM; (2) Evaluate the variability of soil and IGM properties; (3) Recommend best geotechnical investigation practices for IGM; (4) Develop advanced static analysis methods for pile resistance estimation on IGM; (5) Validate and improve the accuracy of dynamic analysis methods; (6) Investigate pile setup and/or relaxation; (7) Develop LRFD resistance factors for piles on IGM; and (8) Recommend changes and improvements to current pile design and construction practices.
