Strength Envelopes for Florida Rock and Intermediate Geomaterials

The objectives of this project are to: (1) acquire and setup a triaxial apparatus at the State Materials Office capable of 1500 psi cell pressure, 40,000 lb. axial capacity with instrumentation to monitor applied stress, strain and pore pressure; (2) collect Florida Limestone and marl samples from multiple surface formations (Miami, Anastasia, Fort Thompson, Suwannee, etc.) that shallow foundation for bridge structures may reside; (3) assist SMO technicians in setting up and performing triaxial compression, extension, unconfined compression and split tension testing of Florida Limestone and marl samples; (4) develop strength envelope, e.g. Eq. 2 for compression and extension for Florida Limestone and marl; (5) develop a stress-strain model including strain softening if necessary and implement into a Finite Element code to model both the homogeneous and 2 layer (rock over sand) bearing capacity problem; and (6) develop bearing capacity equations (e.g. Eq. 1) for both homogeneous and 2 layer (rock over sand) problem for Florida Limestone and marl conditions.
