| Abstract: | A 2-dimenssional SFEM for tunnel structural reliability calculation and amathematical model for tunnel system reliability analysis are developed in this paper. Acorresponding computational program is developed and used in an example of pressure linedtunnels. Furthermore, the effects of the length of the tunnel system and the mean length ofthe failure region on tunnel system reliability are also investigated. |

| Keywords: | SFEM tunnel structure system reliability failure probability |
