Rational Design of Tunnel Supports: Tunnel Support Loading Caused by Rock Failure
Two methods are presented for the analysis of tunnel support loading caused by rock failure. In the first part closed-form solutions are used; in the second, numerical techniques. Emphasis is put upon the statical indeterminacy of the problem and upon the necessity for considering the relative displacements between ground and support. From this follows the need for a realistic calculation of the stiffness of ground and support, as well as the need to consider the sequential development of the interaction between these two elements. It is assumed that the rock mass behavior during failure is softening and dilatant. Interface problems between ground and support that can strongly influence the effective support stiffness are discussed.
