20.500.12556/RUL-96352 Vpliv faktorja nosilnosti Ns na izbiro podpornih ukrepov pri gradnji predora The influence of capacity factor Ns on the choice of supporting meassures in tunneling Koeficient nosilnosti Ns, ki predstavlja odnos med višino nadkritja predora in trdnostjo hribine, uporabljamo pri določanju ocene stabilnosti izkopavanja predora. Diplomsko delo je analiza vpliva parametra Ns na izbiro podpornih ukrepov in ustrezne tehnološke sekvence za primarno podpiranje predora. Pri tem bo uporabljena Kirscheva analitična rešitev za stanje napetosti okrog odprtine v napetostnem prostoru ter na podlagi le te določena interakcija hribine in podporja v predoru. Capacity factor Ns represents the relation between the height of overburden of the tunnel and the strength of rock or soil. It is used to evaluate the stability of the tunnel during the excavation. The main focus is in this diploma is the analysis of effects on the capacity factor Ns and the choice of supporting measures for tunnel construction. Furthermore, it enables us to estimate the technological sequence of the primary support. Kirsch’s analytical solution for the state of stress around the tunnel cavity was used to solve the interaction between the rock and the supporting elements during tunnel construction. geomehanika predor faktor nosilnosti Ns podporni ukrep faktor razbremenitve geomechanics tunnel capacity factor Ns supporting measures de-confinement ratio true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-29 07:15:29 2017-09-29 07:15:31 2022-08-12 11:16:33 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 58288 1697375 530.pdf 530.pdf 1 A686AB0FD4C95E046B50862E8859BD9B 1353d034d10fe8c63264051529c7412bdeed69cbd949b9d748ffa30b8f712b7e e430224e-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/507fe262-f4fc-4986-a507-cd0f8b8de6d9 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=105012 Naravoslovnotehniška fakulteta 0 0 0
