This paper presents the geotechnical properties of young calcareous rocks of southern Florida. The rocks covered are Miami, Key Largo, and Fort Thompson limestones. The paper briefly details the formation and areal extent of the rocks and then evaluates several samplers for obtaining maximum recovery in a relatively undisturbed form. Evaluation of the properties is based on field and laboratory tests. The field tests included seismic refraction studies, downhole and crosshole wave velocity studies, and Menard Pressuremeter tests. The laboratory tests comprised index tests and strength and deformation evaluation tests. In addition to the usual unconfined compression tests, this investigation reports the results of the Ko-triaxial tests on the rock specimens.
The range of values for porosity, compressive strength, and modulus from various tests is presented. The discussion provides a rationale for the difference in values obtained from the tests. The suitability of various tests in providing a representative mechanical behavior is discussed.
