Abstract：Abstract ： Research purposes ： In the program of non - probabilistic reliability analysis of lining structure， stress and intensity interval interference will occur when the non - probabilistic reliability index is 0 < < 1. At the same time when analyzing reliability of tlie lining structural system，failure probability of each unit system usu^ly was calculated by using the traditional methods based on probability theory and fuzzy theory. In this paper， the stress – strength interference model was proposed，the ratio of tlie area of failure region to the total area of tlie region constructed by the basic interval variables was taken as the non - probability failure degree of lining structure and the PENT metliod was combined with the non - probabilistic reliability analysis of the whole tunnel structural system. Research conclusions:( 1 ) The problem of non - probability failure degrees of lining structure under interference situation was successful solved，which showed the non - probability failure degree having compatibility with that fromthe failure probability. (2 ) Interval interference lining structure model could be used to calculate non - probability failure of lining structural unit in the tunnel structural system. ( 3 ) The results provide a new feasible method for the tunnel structure system reliability analysis， while in the non - probabilistic reliability analysis of actual project interval interference problem also have been solved.
