Abstract

Research purposes: Railway tunnel belongs to half concealed work because it is constructed in the underground rock—soil medium．It is difficult to determine the specific disease situation of the lining because the lining is concealed．According to the investigation of the phenomenon of tunnel lining disease，the model for fuzzy evaluation of The lining health of railway tunnel was established with improved fuzzy AHP to determine the weight and improving multi—fuzzy algorithm，for the purposes of finding out the major diseases of the lining and their impact levels．

Research conclusions: Application of this model can quantitatively evaluate the lining health of railway tunnel and objectively analyze the impact factors and levels of the most important desease．The application shows the model can be used for the similar works．

Key words

lining disease of tunnel / fuzzy AHP / multi—fuzzy algorithm / improvement
