... University, Melbourne, Victoria, Australia ABSTRACT: A series of uniaxial compressive strength tests were performed to study the deformation charac- teristics of bedded sandstone with bedding layers in different orientations. Test results revealed that the samples with bedding layers oriented in smaller...
