20.500.12556/DKUM-52793 Vpliv mehanskih lastnosti kamnine na odboj kamnitega kosa The impact of mechanical properties of rock to the collision of rock piece Namen pričujočega prispevka je ugotoviti pogoje pri katerih pride do loma kamnitega kosa in s tem do zmanjšanja njegove mase in spremembe odbojnih karakteristik. Lom kamnitega kosa je odvisen od strukture in kvalitete kamnine, ki sta izraženi z modulom elastičnosti in enoosno tlačno trdnostjo kamnine. The paper presents the analytical solution of the rock piece motion considering influences of geometrical and mechanical characteristics of rock mass on the arbitrary slope. The main objective of the paper is to determine the motion of the rock piece considering possibility of rock piece failure due to collision. Brief description of the analytical solution of the rock piece motion on a steep slope is given. The laboratory tests were performed to determine uniaxial compressive strength and elastic properties of the considered rock mass. Further, velocities that cause rock piece failure were determined. These maximum velocities indirectly belong to certain mass of rock piece and can be lower than velocities calculated in rock-fall analysis for certain slope geometry. Consequently, the energy magnitude is limited, because at certain velocity and mass of rock piece bigger pieces crash at collision. podor trk enoosna tlačna trdnost modul elastičnosti rock-fall collision uniaxial compressive strength elasticity modulus true false true Slovenski jezik Angleški jezik Znanstveno delo 2015-07-10 18:21:53 2015-07-10 18:21:53 2022-06-01 03:07:30 2021-05-10 03:28:18 2007 0 0 str. 189-196 št. 1 Letn. 50 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0016-7789 624.131 5636866 1446741 10.5474/geologija.2007.015 0016-7789 URN:SI:UM:DK:1XSK7NCI Geologija_2007_Macuh,_Zlender_Vpliv_mehanskih_lastnosti_kamnine_na_odboj_kamnitega_kosa.pdf Geologija_2007_Macuh,_Zlender_Vpliv_mehanskih_lastnosti_kamnine_na_odboj_kamnitega_kosa.pdf 1 6A90F5A74C61C8CEEB785BDF0F168E6F 791398a0d4d7d7193719fe0e82bc91e207357c96a4b0fd17be3005da29bfa267 72023fc1-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=114487 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
