Summary The expression “squeezing rock” is a concept too vague to be used by practicing engineers. In this paper, it is assumed to mean large convergences of the tunnel walls. Two case histories are briefly presented. The Frejus tunnel was driven with a large overburden; on the contrary, the Sidi Mezghiche tunnel was shallow. Different techniques were used to control the convergences. In both cases, the tunnels were located in “complex formations”; the complexity stems from the heterogeneity and anisotropy of the rock masses, and no efficient technique is available to determine the geotechnical characteristics and the natural state of stress in the formations.
