... prediction of squeezing conditions in rock tunnels based on case-histories in tunnels under high stresses. The methodology is based on the use of a linear classifier for statistical analysis of a database of well-documented case histories compiled from the literature. Results show that rock quality...

... Caminos, C. y P., Technical University of Madrid, Spain ABSTRACT: This paper presents the application of an empirical equation for modeling the evolution of convergences (both as a function of time and distance to the face) in rock tunnels. To that end, convergence data from several case histories...
