Abstract

This paper describes the geotechnical issues related to pile foundation construction for the widening of the 1-295 Buckman Bridge over the St. John's River in Jacksonville. Florida. The project included a total of 1351 prestressed concrete piles, with sizes up to 30-inchcs (762-mm) square and design capacities up to 205 tons (1,820 kN). The paper highlights the application of dynamic testing as a routine and essential quality control measure during construction, and presents summaries of the dynamic test data obtained. Issues addressed include increased pile capacity with time after driving, unit friction and end bearing values, hammer efficiency, driving stresses, and dynamic parameters for soil and lime rock.
