For site investigation of tunnels, it is effective to layer the earth, map faults and fracture zones by using acoustic wave logging along with apparent resistivity logging, while water - bearing layers and ground water recharge direction could be mapped effectively by using SP logging and high -precision down hole temperature measurement.
