Abstract: Performance function of lining structure reliability is established according to “action-reaction” model. Based on the statistical characteristics of physical property obtained by exploration of No.4, No.5 and No.10 line of Beijing Subway, the structural reliability of Beijing metro tunnel is analyzed by using Monte-Carlo method. The effects of primary support and lining under the condition of natural environment are discussed, the results consider that lining bear the whole loads during the operation and primary support only improve the work environment of lining. The elastic resisting coefficient around the lining should be increased, which can not only simplify calculation, but also meet the working situation of lining structure.

Key words: metro tunnel, action-reaction model, primary support, secondary lining, effect relationship, structural reliability
