Axial Response of a 30-inch-Diameter Concrete-Filled Pipe Pile during Driving, Static Load Testing, and In-Service

In the summer of 2014, the Minnesota Department of Transportation (MnDOT) began construction work on Bridge 10004 to elevate MN Highway 101 above the existing embankment grade eliminating seasonal flood closures. Thirty-inch diameter piles were used at many of the pile-bent piers to accommodate lateral load requirements associated with relatively long exposed lengths of piling. The axial compression loads were not particularly large, resulting in relatively few piles per pier. During construction, the 30-in. diameter piling was not demonstrating satisfactory capacity at planned toe elevations. Piles were driven considerably deeper than anticipated, with significant impacts on time and cost. Progressive pier construction made any longer-term pile re-strikes for capacity verification difficult. A static load test, modified from an earlier concept pre-design load test program, was conducted at Pier 8 and the data used to evaluate the situation. The test pile was instrumented with internal strain gages, which continue to be monitored several years into bridge service. Design, construction, performance, and load test performance are discussed.
