    In 1998–99, the U.S. Geological Survey conducted a crosshole radar tomographic experiment at the lateral-pile-load testsite on Treasure Island to nondestructively image the soil column for changes in void ratio before and after a liquefaction event that was caused by controlled blasting. A geotechnical borehole radar technique was used to acquire high-resolution two-dimensional radar velocity data. This method of nondestructive site characterization uses trans-illumination surveys through the… CONTINUE READING
