... frequency and joint stiffness. Using the example of the Melbourne Mudstone, this paper compares approaches using empirical rules based on intact rock strength, laboratory testing, insitu field testing, semi-quantitative assessment techniques based on rock mass classification and back analyses. L'evaluation...

... SYNOPSIS: The strength and deformation properties of the Melbourne mudstone under uniaxial compression and Brazilian test conditions are examined for the range of weathering characteristics commonly encountered. The relevancy of these simply obtained properties to engineering design...

...-linear elastic finite element analyses for sockets in Melbourne Mudstone, using these models of rock behaviour. Comparison with field tests shows that the best agreement is obtained with a nonlinear elastic model which allows for work softening in the rock. Theoretical and measured stresses are also...
