Underground openings and excavations are increasingly being used for civilian and strategic purposes all over the world. Pressure on tunnel support depends on deformation and stress release and tunnels can be classified [9] into: (a) conforming; (b) non-conforming. Evaluation of safety of a tunnel, especially a non-conforming one, in soft ground or poor rock mass needs an interactive analysis. Interaction is an issue of great relevance in the case of tunnels in lower Himalayas. Many valuable field observations on actual Himalayan tunnels have been documented by [2, 7, 8]. Based on these, several empirical correlations have been developed, which are very useful in evaluating, particularly, the rock pressure on such tunnels. Although the correlations account for a wide variety of ground conditions, there is, inevitably, considerable empiricism. Jimenez and Recio [3] have attempted a probabilistic modelling of the variable ground conditions and evolved classifiers to distinguish between squeezing and non-squeezing conditions. However, evaluating the response of tunnels considering the material uncertainties has not been included in their scope. The present study is an attempt to evaluate tunnel safety and stability through reliability analysis under squeezing conditions.
