Abstract

The spectral-analysis-of-surface-waves (SASW) technique is compared with the ground<br>penetration radar (GPR) method for detection of buried objects. Tests were performed in a 7 m<br>diameter by 2 m deep sand bin in the G. G. Brown Lab of the University of Michigan. The bin is<br>filled with uniform silica sand compacted to a uniform density of about 16 kN/m³. During the<br>filling process, a three-cell void was buried at a depth of 305 mm to the top in the center of the bin.<br>SASW and GPR tests were performed with all three cells empty, one cell (center cell) empty, and<br>all cells full of sand. The two experimental techniques are being compared with each other for<br>eflicacy of void detection.
