AI Technical Summary

Technical Problem

Existing technologies are insufficient to accurately predict the explosion response of in-service tunnels caused by material performance degradation, segment joint deterioration, and interface defects. Furthermore, traditional methods are time-consuming, labor-intensive, lack physical interpretation, and have limited generalization capabilities.

Method used

By using a graph neural network-based approach, tunnel degradation patterns are quantified as graph structure attributes. A graph neural network surrogate model is constructed, and combined with efficient sampling and parallel computing, a scenario-response database is quickly generated. Damage features are then reduced in dimensionality and clustered to reveal damage patterns and evolution paths.

Benefits of technology

It enables efficient and accurate prediction of the explosion response of in-service tunnels, improves the physical consistency and accuracy of the analysis, and provides a reliable basis for explosion-proof protection design.
