Risk Assessment of Shield Tunnelling in Mixed Ground Using a Coupled Subjective–Objective Weighting and Fuzzy Set Pair Analysis Model

Shield tunnelling in upper-soft and lower-hard mixed ground is characterised by strong geological heterogeneity and coupled construction risks, including uneven cutterhead loading, face instability, cutter wear and abnormal fluctuations in tunnelling parameters. This study assess...
