Abstract

In the longterm operation tunnels, multipile diseases may occur in the lining and have an effect on one another. Therefore it is necessary to establish an evaluation method for tunnel lining technology condition based on the disease correlation. Through case collection, 166 lining disease information in 15 operating tunnels are investigated. The data mining method is used to study the correlation among tunnel lining diseases. Then the evaluation index are selected according to the current standard； the index weight is determined by AHP; the membership vector of each indicator is determined using engineering variable fuzzy set theory; and the comprehensive evaluation model of tunnel lining structure technical condition based on disease correlation is established eventually. Combined with the measured data from Baoziliang tunnel, the results show that: Considering the correlation among diseases, the order of comprehensive values of tunnel lining technical conditions does not change, but the values are increased significantly, with an average increase of 44.11%. This result is consistent with the actual situation.

Key words： operating tunnel; lining disease; technical condition evaluation; correlation analysis; variable fuzzy set method
