1 C.P.T.U. TEST REPORT CPTU 251-3/14 Customer: ARAQUARI EXPERIMENTAL SITE Job: Araquari Experimental Site Location: Mineração Veiga Araquari/ SC 1. SUMMARY This report contains the results of the CPTU tests performed to characterize the soil profile at the Araquari Experimental Site located in Mineração Veiga Araquari/SC. An amount of 6 (six) CPTU penetrations were performed. The depth and coordinates of the tests performed are presented in the table 1. Boring Nº Table 1: Depth and coordinates of the tests performed Coordinates E N Elevation (m) CPTU 1 Geoforma CPTU 2 Geoforma CPTU 3 Geoforma CPTU 4 Geoforma CPTU 5 Geoforma CPTU 6 Geoforma The tests results had been used to prepare the following derived data: (1) A combined plot of the corrected cone resistance (q t ) versus depth; (2) A combined plot of excess pore pressure (u 2 ) due to penetration versus depth; (3) A combined plot of sleeve friction (f s ) versus depth; (4) A combined plot of excess pore pressure ratio (B q ) versus depth; and (5) A combined plot of friction ratio (R f ) versus depth.
