Geological Risk Assessment for TBM
Research Guide
What is Geological Risk Assessment for TBM?
Geological Risk Assessment for TBM evaluates probabilistic risks of squeezing, faulting, and water ingress affecting Tunnel Boring Machine performance in hard rock using geophysical data, rock mass classification, and probabilistic methods.
This subtopic integrates site-specific data for hazard mitigation in TBM tunneling. Key methods include fuzzy logic (Yazdani–Chamzini, 2014, 91 citations) and data-driven prediction models (Zhao et al., 2019, 85 citations). Over 1,000 papers address TBM risks since 2010.
Why It Matters
Geological risk assessment reduces TBM project delays by 20-30% in squeezing ground, as shown in Ramoni and Anagnostou (2010, 123 citations) on shield-ground interactions. BIM integration identifies tunnel risks early (Zhang et al., 2016, 108 citations), preventing safety incidents in urban projects like metro lines. Data-driven frameworks predict geology from TBM data (Zhao et al., 2019, 85 citations), optimizing advance rates in faulted terrains.
Key Research Challenges
Squeezing Ground Prediction
Squeezing deforms TBM shields in weak rock, complicating advance rates. Ramoni and Anagnostou (2010, 123 citations) model shield-ground interactions, but real-time prediction remains inaccurate. Probabilistic integration of geophysical data is needed (Khademi Hamidi et al., 2010, 82 citations).
Fault Zone Detection
Faults cause sudden TBM stoppages and water ingress risks. Zhao et al. (2019, 85 citations) use TBM operating data for geological prediction, yet pre-excavation detection lacks precision. Hybrid SVM models assess rock brittleness near faults (Jahed Armaghani et al., 2020, 97 citations).
Water Ingress Modeling
Water-bearing ground increases TBM shield loading during consolidation. Ramoni and Anagnostou (2010, 36 citations) analyze effects, but probabilistic risk quantification is challenging. Fuzzy-AHP methods aid TBM selection (Khademi Hamidi et al., 2010, 82 citations).
