Abstract
This paper attempts to determine the relationship between the lithology, the type of mechanism of disintegration of sandstone samples and the morphology of the resulting separation surfaces, which has a significant impact on the magnitude of displacements occurring within the rock mass. Six lithologically different sandstones from the Carpathians, Sudetes and Holy Cross Mountains were analysed. The first element of the research was petrographic studies. The next tests consisted of carrying out strength tests, including tests of rock resistance to uniaxial compression strength and flexural strength under concentrated force. Then, a total of 12 surfaces obtained were examined using a laser profilometer. Laser profiling data was correlated with petrographic and strength test data. They showed that the strength value is influenced by the type of rock itself and that the morphology of the separation surfaces differs depending on the type of disintegration. Surfaces obtained by uniaxial compression testing are rougher than those obtained by bending forces. Moreover, the study revealed a fairly clear relationship between sandstone textures and roughness parameters of surfaces, regardless of the disintegration test. The highest roughness values are found on the surfaces of sandstones from Radków, Tumlin and Bieganów. On the other hand, there is no correlation between waviness values and rock textures. Therefore, waviness parameter is a poor tool for describing the morphology of the separation surfaces in sandstones.
