Dual Tip Penetrometer—A New In Situ Approach to Identify Cemented Sand
The dual tip penetrometer (DTP), a novel in situ test, was developed at the University of Florida (UF) to help identify cemented sands. Pairs of DTP and standard cone penetration (CPT) tests were performed at multiple Florida Department of Transportation (FDOT) project sites in Florida. These sites included the West Bay Bridge, and the Port Orange Relief Bridge. Cemented sand layers were present at different depths at these sites. Both DTP and CPT results were analyzed to screen cemented sand identifiers (tip resistance qc, friction ratio Rf, and the ratio between the second and first resistances T2/T1). The ratio T2/T1 was determined to be best identifier for identifying cemented sand. Based on the above test results and analyses, it appears that the DTP could be an efficient tool to identify cemented sand and better predict pile capacity.
