Description
  • V příspěvku jsou presentovány výsledky parametrické studie vlivu orientace ploch nespojitosti na odezvu horninového masivu při ražbě podzemního díla ve směru ploch nespojitosti. Řešeny byly tři modelové varianty: podzemní dílo v horninovém masivu s jednostranným sklonem ploch nespojitosti, podzemní dílo umístěné v synklinálním ohybu a podzemní dílo v antyklinálním ohybu. V rámci těchto variant byl variabilně uvažován různý úhel sklonu ploch nespojitosti v rozsahu 0 až 90 stupňů. Studie byla provedena na matematických modelech metodou konečných prvků s využitím programu Plaxis. Matematické modely byly rovinné - rovinná deformace. K simulaci mechanického chování horninového prostředí byl použit Rock Jointed model. Podzemní dílo je raženo na plný profil a není zajišťováno ostěním. Řešené varianty jsou porovnávány na základě svislého posunu ve vrcholu podzemního díla a maximálního svislého posunu povrchu terénu. Z prezentov (cs)
  • The results of parametric analysis on influence of discontinuities orientation on the response of rock mass during driving an underground structure in the direction of discontinuity planes are presented in the contribution. Three typical alternatives were considered: the underground structure in rock mass with one-sided dip of discontinuities, the underground structure situated in synclinal bend and the underground structure situated in anticlinal bend. In all three cases, the variability of discontinuities dip angle in the range of 0 - 90 o was considered. Mathematical models were used for the analysis by Finite Element Method using software Plaxis. Mathematical models were planar - plane strain. Rock Jointed model was used to simulate mechanical behaviour of the rock environment. The underground structure is driven in full -face with no lining. All the analysed alternatives are compared to one another considering the vertical displacement at the top of the underground structure and maximum vertical
