The Effectiveness of GPR In Sinkhole Investigations

摘要

GPR and SPT data from 93 sites in West-Central Florida was analyzed to evaluate the effectiveness of GPR in determining the presence of sinkhole features. SPT results were used as the criteria to determine if the GPR method was effective. The size of the feature being investigated is considered in determining the combined effectiveness of these methods. The effects of near-surface clay on GPR results are discussed as they impact test results. From these factors a candid discussion of the advantages and disadvantages of these methods in accurately assessing geological conditions as they relate to karst activity in West Central Florida is provided.
