Abstract

Summary

The impact of sinkholes can be extremely severe so that mapping buried karst in the karst areas is of primarily concern to construction of engineering infrastructure. Initially, potentially karst hazardous sites should be determined by geological and geomorphological approaches. Then electrical resistivity tomography (ERT), a well-established method for investigating near-surface geological and geotechnical conditions, is performed on selected sites. At the last stage, drilling is performed, confirming the presence or absence of sinkholes at a particular site. We see this sequence of steps as the most economical and efficient and show some results of ERT as applied to the karst risk assessment when designing linear engineering structures like roads, pipelines, power lines.
