Detection of karst cavities by geophysical methods
Summary At two dam construction sites in Central America geophysical tests were conducted in a karstic environment in order to evaluate the applicability of indirect methods for detecting cavities, fissures and other anomalous features. Geophysical techniques evaluated were ground probing, radar, acoustic seismic and refraction seismic methods. Based upon the results of geophysical tests and their comparison to known geologic conditions it was concluded that the radar technique showed the greates promise for use as an aid and “guiding-tool” in the execution of the grouting programs of either sites. The content of this paper addresses the rational leading to this conclusion.
