Mobilized Resistances Based on Static, Dynamic, and Numerical Methods at the Jingi Jingi Creek Bridge Replacement Project, Queensland, Australia

Source

The foundations of a 17- by 10-m span bridge that were used to replace a 145-m-long culvert on the Warrego Highway, west of Brisbane, Australia, have recently been completed. The bridge foundations consisted of 5- by 550-mm octagonal prestressed concrete (PSC) piles at the abutments and pier locations. A total of 90 PSC piles were installed. Prior to installing the production piles, three test piles were driven to nominal refusal per Queensland Department of Transport and Main Roads (QDTMR) guidelines. The test piles were dynamically tested using the Pile Driving Analyzer, and the activated (mobilized) resistances and their distributions were checked against those predicted from static- and finite element–based approaches. During the installation of the production piles, representatives of the piles were equally tested per QDTMR guidelines, and all results from the various methods at different stages of the project were analyzed and compared.
