Cutter performance evaluation is important for shield TBM during the design and refurbishment stage. To face challenges of choosing proper cutters tunneling in complex condition, according to concept parameter profile analysis, a systematic method was proposed. In this novel method, by comparing with their expected best value corresponding unacceptable limit, all selected parameters can be synt...

in this paper, based in the l ukasiewicz logic, the definition offuzzifying soft neighborhood structure and fuzzifying soft continuity areintroduced. also, the fuzzifying soft proximity spaces which are ageneralizations of the classical soft proximity spaces are given. severaltheorems on classical soft proximities are special cases of the theorems weprove in this paper.

This research was undertaken to predict the result of vault settlement during excavation super-large-span tunnels in soft rock strata, which are prone deformation and hard aftermaths. Numerical simulation applied tackle with problems such as proneness prediction on settlement. As a result, model for continuous tunnel face keeps advancing proposed, influencing factors span depth taken into consi...
