MAPPING AND PREDICTION OF LIMESTONE BEDROCK PROBLEMS

Site evaluation for transportation routes and engineering structures located in limestone bedrock regions is often difficult. The highly irregular soil-bedrock interface and the presence of subsurface cavities make the results of such an investigation highly uncertain. A methodology has been prepared to assist the engineer with the planning of a thorough site evaluation that will minimize the degree of uncertainty. Preliminary studies consisting of the compilation of data from existing sources such as physiographic, engineering soils, pedologic, surficial and bedrock geology, topographic, drainage, and overburden thickness maps and reports are essential. A review of the current methods of remote sensing such as aerial photography, reflective and thermal infrared imagery, radar, radiometric data, and multispectral imagery is included. Combining this information with a knowledge of certain geologic indicators will identify areas that are more suitable to the siting of the route or structure under study. Preparation of a sinkhole density map is advocated for projects involving large areas. Areas of uncertainty can be further investigated employing geophysical techniques such as gravity, ground-probing radar, magnetics, seismic refraction, or electrical resistivity. The problems for which each of these techniques is appropriate are discussed. The compiled information can then be used as a guide to plan the location of subsequent borings.
