| 摘要： | Drilled shaft foundations socketed into limestone support many Florida structures and bridges through weak overburden soils. The current design method for side shear capacity of drilled shafts in the highly variable Florida limestone uses compressive and tensile strength tests of rock cores. However, these tests represent only the recovered, intact portion of the rock core, not the rock mass. The pressuremeter measures rock strength insitu and should accurately reflect the properties of the rock mass while reducing lab-testing effort. The research described herein includes pressuremeter tests in both laboratory anf field tests to estimate the strength and stiffness of Florida limestone. It also includes the measurement of modulus and strength on rock core samples by the Florida Department of Transportation and the University of Florida (UF). |
