Underground Cavities Investigation Using Geophysical Method, GPR (Case Study: Kerman City)

One of the most important parameters in performance of every constructing project is the analysis of undersurface condition to assure the land fitness for structure establishment. Flumes and cavities in low depths can be specified fairly by GPR method due to obvious difference in electromagnetic characteristics with their surrounding environment. Geo radar studies have been used to explore undersurface phenomena such as flumes and cavities in Abolfazl Tekieh foundation site in Mahdieh Street, Kerman city. The aim of these studies is undersurface exploration of the depth of 3 to 15 m. The region under study was marked and profiled and all measurements were performed on determined profiles. After processing and expounding of removed sections according to obtained radar grams, some abnormalities were observed that mainly showed some undersurface looseness or small local cavities.
