Predictive and Diagnostic Analysis of Shield Cutter Head Failures in Tunnel Construction
Shield cutter head failures exist in almost every tunnel project. A systematic approach that incorporates dynamic fault tree (DFT) and discrete-time Bayesian network (DTBN) is developed in this research, in order to facilitate the analysis for shield cutter head failures in tunnel construction. A causal network model is built to simulate the behaviors of shield cutter head failures over time during the tunnel boring machine (TBM) operation. One of the tunneling projects recently completed in the Wuhan metro system in China is selected as a case study to demonstrate the applicability of the developed approach. Results indicate that the developed approach is capable of predictive analysis for the estimation of the TBM performance, and diagnostic analysis in case a low performance or a failure is observed. This approach provides a powerful potential solution to modeling and analyzing various kinds of system components behaviors and interactions in a complex project environment.
