Fuzzy Evaluation of Supporting Structure in Metro

Abstract:

Based on characteristics of supporting work for deep excavation in metro, an index system for supporting version was established. The weighting of index was set up with hierarchy analysis. A single level fuzzy evaluation model was formed with fuzzy mathematical method. The uncertainty of the index factors was quantified. A case study showed that fuzzy comprehensive evaluation method was reasonable and effective, and can be referred to practical engineering.
