Název v původním jazyce

Shear failure of rocks and creating their shear plane

Popis výsledku v původním jazyce

The study was focused on exploration of the shear strength of slate with distinguish planes of weakness, i.e. cleavage. Slaty cleavage represents the ability of rock to split into more or less parallel planes and disturbs the rock massif. The presence ofthese planes of weakness affects the strength and deformational behaviors of rocks and indicates asymmetric fracture of rocks and unpredictable strength behaviour. Tests were carried out on the laminated slate with predetermined shear plane. This rock originates from ?Bělá? quarry from the Moravo-Silesian Culm, Czech Republic. The oriented specimens were taken by manual drilling machine. The drilled specimens of slate were divided into five groups based on the different angle between shear plane and cleavage. Testing of each group was carried out in seven directions with an interval of 15°. The first direction which was called ?zero? direction was perpendicular to the cleavage. Solids were tested at portable rock shear box assembly Mat
