Title: PILE FOUNDATION--FROM PRELIMINARY BORINGS TO PRODUCTION DRIVING
Accession Number: 00372274
Record Type: Component
Availability: Find a library where document is available Abstract: Foundation design for a major bridge structure requires extensive field and office investigation. The design process undertaken for the Arrowhead Bridge, which carries US-2-between Superior, Wisconsin, and Duluth, Minnesota, over the St. Louis Bay, is presented. Subsurface investigation results, geologic studies, pile load tests, wave-equation analysis, and dynamic pile testing are presented. Results of the geotechnical investigations allowed the use of high-capacity piles in soil for the bridge foundation. Subsurface conditions consisted of soft lacustrine and glacial clay deposits over dense glacial outwash sands. Depths to the underlying dense strata ranged from 130 to 260 ft (39.6-79.2 m) across the site. Six load tests were performed on steel H-piles and cast-in-place type piles. Maximum loads of 344 tons-force (3060 kN) were applied by using both maintained-load (ML) and constant-rate-of-penetration (CRP) methods. Load test results are presented by using five interpretative techniques, and comparisons between ML and CRP methods are shown. Wave-equation analyses were performed by using the WEAP computer program, and results are compared with driving records. Dynamic pile analysis was done by using the Goble-Case Western pile driving analyzer (PDA), and pile capacity predictions are compared with load test results. The PDA was also used on production piling, and experiences while analyzing the very long piles for capacity and damage are discussed. (Author)
