Using physical simulation, numerical modeling and the in situ data, the differences between the apparent resistivity of low resistivity model obtained by transverse profiling method （TPM） whose electrode array is vertical to the profile and those by longitudinal profiling method （LPM） whose electrode array is parallel to the profile are analyzed, respectively. Our results show that the former has much marked amplitudes of anomaly. Therefore, TPM can be used to detect a strike fault more effectively and locate it more precisely, and is expected to be a new approach for detecting a sliding fault.展开更多

The aim of this study was to compare depth and thickness resolution power of Schlumberger and Wenner arrays. The investigation involved twenty-four vertical electrical soundings (VES) which consisted of twelve Schlumberger array VES and twelve Wenner array VES. The VES results delineated geoelectric layers beneath each VES locations, their layer resistivities, layer thicknesses and depth to aquifer layer(s). Depth to aquifer layer was also determined from static water level measurement and this aided the aquifer layer delineation from VES results. The geoelectric sounding results showed that the study area is dominated by a KH-curve type which consists of top soil, clay/weathered layer, fractured basement and fresh basement. Results from both Schlumberger and Wenner array data were correlated with the static water level measurement;Schlumberger array was found to have higher correlation value than Wenner array.展开更多
