【 摘 要 】

The geoelectrical resistivity survey has been successfully used to explore the groundwater accumulation in the fractured zone of the bedrock area. The geoelectrical resistivity surveys with Wenner configuration were conducted perpendicular to the possibility of fracture zones. The resistivity profiles show that the sediment thickness vary from 5 m to about 30 m with resistivity value of less than 200 ohm.m. Whilst the bedrock zone is indicated with resistivity value of more than 1500 ohm.m. The possibility of groundwater is observed both in the fractured zone of the bedrock and in the sediment, which is indicated with the resistivity value of about 30-80 ohm.m. Generally, the fractured groundwater has been found between the undulations zones appear on the surface.
