Abstract

Summary

This paper shows the construction of the second Geophysical Test Site of the Institute of Astronomy, Geophysics, and Atmospheric Science at University of São Paulo, installed at USP campus in São Paulo city, Brazil. It shows too the preliminary GPR results on buried pvc/metal pipes and ceramic tubes in the subsoil in which they simulate the gas/water pipelines and pluvial water canalization gallery underground of the great cities of the world. The targets installed in subsoil are constituted by metal and plastic tanks, concrete tubes, ceramic vases, plastic conduits etc., and its top depths varying from 0.5 to 2.0 m. The targets simulate geotechnical, environmental, and archaeological studies where its location is the goal. GPR profiles of 900 MHz and 270 MHz were acquired along of line 3 constituted by pvc/metal pipes and ceramic tubes. Preliminary GPR results show typical hyperbolic reflections pattern characteristic for each target. The IAG/USP Test Site-II was constructed with teaching and research purposes in Applied Geophysics. These results can help in location of buried utilities in subsoil of the great cities minimizing the risks of dangerous accidents.
