Resilience Evaluation Strategy of Undersea Shield Tunnel Based on Knowledge Graphs

The complex geological environment, hydrologic environment, and the vulnerability of tunnel structure bring high risk to the structural safety of submarine tunnel. To scientifically evaluate the resilience of undersea shield tunnels, this paper proposes a resilience evaluation system for tunnel engineering in complex environments based on a knowledge graph. The proposed approach analyzes the resilience characteristics of material properties and structural modes, adopts system resilience enhancement theory, and coordinates disaster prevention during both construction and operation periods. Resilience evaluation standards are established and tunnel deformation is monitored in real time. The above information about resilience is collected and sorted to form a data layer. A knowledge graph is constructed based on the data layer to evaluate the resilience of the tunnel structure automatically. The Qingdao Jiaozhou Bay Second Undersea Tunnel Project is used as a case study for engineering resilience evaluation and enhancement, providing a reference for the application of resilience theory in tunnel engineering.
