The evaluation of rockfall starts with a review of the relevant terminology in this field of study and continues with theoretical bases of collapse, reasons for their occurrence and mechanics of rockfalling.

The central part of the thesis is an overview of various measuring methods that are being used for the analysis of rockfalling. Important entering data for calculation of simulation of rockfalling is the longitudinal characteristic profiles of the ground, which are implemented in selected scale.

Abstract (ePrints): |
Obravnava podorov v kamninah, s poudarkom na padajočem kamenju, se začenja s pregledom izrazoslovja na tem področju. Nadaljuje se s teoretičnimi osnovami podornih pojavov, opisov vzrokov za njihov nastanek in mehanike padanja kamenja. Poseben praktični problem predstavlja modeliranje padanja kamenja, zato so v nadaljevanju na kratko opisani razpoloţljivi računalniški modeli, ki se uporabljajo za analizo potovanja kamninskih gmot po pobočju. Sledi opis tehničnih ukrepov za zaščito pred padajočim kamenjem, predvsem uporaba dinamičnih varovalnih ograj in njihovo delovanje. Osrednji del naloge predstavlja pregled različnih merskih metod, ki se uporabljajo pri analizi padanja kamenja. Pomembni vhodni podatki za izračun simulacije padajočega kamenja so vzdolţni karakteristični profili terena, ki jih izdelamo v izbranem merilu. Posebej so opisane osnovne značilnosti merskih metod, in sicer meritev s preciznim kompasom in naklonomerom, klasičnih terestričnih geodetskih meritev, GNSS meritev in terestričnega laserskega skeniranja. Na kratko je predstavljeno brezkontaktno pridobivanje podatkov s pomočjo helikopterja ali letala ob uporabi fotogrametrije in uporaba podatkov letalskega snemanja za ortofoto podlage območja Slovenije. Predstavljeni so tudi vidiki pri izbiri najprimernejše merske metode. Nalogo zaključujem s praktičnim delom, kjer so podani primeri uporabe geodetskih meritev v praksi. Geodetski posnetek je namreč osnova za izdelavo projekta zaščite pred padajočim kamenjem. Prikazano je tudi modeliranje padanja kamenja z računalniškim programom RockFall. |
