Thermal Integrity Testing of Drilled Shafts
Drilled shafts are large-diameter cast-in-place concrete structures that can develop enormous axial and lateral capacity and consequently are the foundation of choice for many large bridges subject to extreme event loads such as vessel collisions. Many drilled shafts are constructed in the State of Florida using the slurry method as a means to stabilize the excavation. This means that both excavation and concreting are blind processes which increases the chances of unwittingly producing defects in the shaft. This project investigates how the heat generation from curing concrete can be used to scan a constructed shaft for defects. Further, thorough understanding of this phenomenon lends itself to evaluating massive concrete structures that may be seriously compromised by detrimental extremes in the internal temperature.
