Residual Stress in Florida Bored Piles

The project objectives are to study the thermal influence on residual stress development in bored piles and identify an appropriate design method for axial capacity using updated Measurement While Drilling (MWD) correlations to South Florida limestone. The authors will conduct a test program on three augered cast in place (ACIP) piles that includes (MWD) with rock core testing for strength and thermal properties, monitoring pile temperatures and strains during curing, measuring strains during axial load tests, grout mix design and curing study to establish the relationships between curing temperature – modulus – mix design, modeling of curing bored pile, and establish T-z model(s) for bored piles with residual stress.
