Optimizing the Use of the Thermal Integrity System for Evaluating Auger-Cast Piles

The primary objectives of this study are to: (1) identify acceptable levels of thermal instrumentation capable of properly quantifying the as-built shape of Auger Cast in Place (ACIP) piles and (2) define appropriate regression techniques for field-collected data. To this end, both numerical modeling and field evaluation of ACIP piles will be performed. As single bar reinforcing schemes are most common, it is conceivable that inclination measurements of a central tube or thermal wire may be employed. This provides a mechanism to differentiate between lower temperatures caused by bar movement (away from the warmer central position) and section loss that causes the same lower temperature measurements.
