Development of 'Face Pressure Control Support System' Using AI to Predict Shield Tunneling Face Pressure 10 Seconds Ahead

Maeda Corporation (Headquarters: Chiyoda-ku, Tokyo; President: Soji Maeda) has developed a DX tool called the 'Face Pressure Control Support System' that uses AI to support the control of face pressure in shield tunneling. The system uses AI to learn from various sensor data and operator operation history accumulated in the company's shield tunneling data platform, 'MAIOSS-II', to predict face pressure approximately 10 seconds in advance. By presenting the appropriate operation timing to the operator based on these predictions, the system supports control that previously relied on the experience and knowledge of skilled technicians, making it possible to suppress impacts on the surrounding environment such as ground subsidence or upheaval. Verification at actual sites showed that the AI's predictions matched those of skilled technicians in approximately 90% of cases, confirming its effectiveness at a practical level. The company plans to roll out the system to sites of Sumitomo Mitsui Construction, part of the Infroneer Group, in the future.
