AI Technical Summary
The geological survey data during the tunneling process of small-diameter TBMs is highly discrete and has a limited detection range, making it difficult to fully reflect the geological distribution characteristics. Traditional methods cannot adapt to real-time changes under complex geological conditions, affecting construction safety and progress.
A multi-source sensing system was constructed to collect device response, geological contact, and environmental sensing signals. Feature extraction and fusion were performed using an adaptive weighted fusion algorithm and a deep learning network. Dynamic corrections were made by combining real-time tunneling parameters and historical data. A full-section geological information distribution map was generated using the Kriging interpolation algorithm.
This improves the accuracy and reliability of geological parameter inversion, reduces engineering rework and cost waste, and ensures construction safety and progress.
