KEPCO Research Institute of Electric Power Research develop a 'water-pressurized soil volume measurement method' to prevent sinkholes and ground subsidence in difficult ground conditions. For tunnels excavated by Tunnel Boring Machine (TBM) for electricity tunnels.

The 'water pressurized soil amount measurement method' is a technology that continuously measures the weight of the excavated soil at every 0.5 second. Weight measurement is automatically transmitted to database through via Bluetooth 4.0 Then an algorithm use input data predict for ground subsidence prediction.

Shinailbo write a KEPCO Electric Power Research Institute official said, “We plan to expand the application of the hydraulic pressure measurement method to electric power district sites in the second half of 2021 after demonstrating it.” “Based on the measured soil amount, an algorithm that can predict the upper ground subsidence will be developed. will be,” he said.
