A comparison between 2D electrical imaging and ground penetrating radar GPR for shallow buried cavities detection on Kangar,Perlis
Two-Dimensional (2D) electrical imaging and ground penetrating radar (GPR) surveys were conducted at a school field in Kangar,Perlis area (northernmost state of Peninsular Malaysia),to map cavities.Ground subsidence occurred during the construction of the school indicating the presence of subsurface cavities.All geophysical methods have their limitations.In order to minimize the limitations,integrated surveys with different methods were carded out.The integration of 2D imaging and GPR surveys allowed us to better identify the buried cavities.Twelve profiles were laid out for both two methods with lengths of 60 m and distance 5 m between the profiles.The results show that both methods show similar anomalies subject to the depth limitation of the GPR method.
