Summary
Excessive rock pressure may cause the failure of the tunnel support resulting in large rock deformations. This phenomenon is referred to as squeezing rock behaviour. After discussion of the factors affecting squeezing the relation between rock deformation and rock pressure is described. The paper further deals with widely applied methods of excavation and support measures in squeezing rock.
