Twi-fuzzy comprehensive evaluation for foundation stability of kunming's newly-built terminal area

摘要

Based on the features of fuzzy evaluation index classification theory, this paper combines the AHP method with the optimal comprehensive evaluation model, and conducts the two model comprehensive evaluation from the viewpoint of system theory. Taking Kunming International Airport terminal area as an example, according to the analysis on the stability of the foundation influencing factors and hierarchical fuzzy comprehensive evaluation model, two fuzzy comprehensive evaluation models is established, the subjection function of each influencing factor is given, and two fuzzy comprehensive evaluation model of the foundation stability is completed as well. The results show that the influence of fault plays a controlling role in fuzzy comprehensive evaluation, and the development of fissure and rock types play the most significant role in foundation stability in the primary index; the calculation results show that the stability of the whole terminal area foundation is good, but as to the local region in the F10 fault zone and the C_(3w) area, the foundation is basically stable because of the influence of structure and the action of corrosion.
