Abstract

Zadatak diplomskog rada je određivanje kvalitete stijenske mase i zona podložnosti s obzirom na nestabilnost
kosina na pokosu zasjeka i prirodnom pokosu stijenske mase uz županijsku cestu ŽC 6055 (dionica Oklaj-
Kistanje), kraj jezera Brljan u Šibensko-kninskoj županiji. Na temelju inženjerskogeološkog kartiranja
stijenske mase, odnosno na temelju homogenosti litoloških i strukturnih značajki te promjene orijentacije osi
ceste i pokosa zasjeka, istraživani pokos zasjeka i prirodni pokos su podijeljeni na 6 inženjerskogeoloških
zona. Zbog različitih morfoloških uvjeta, odnosno zbog različitih kutova nagiba pokosa zasjeka i prirodnog
pokosa stijenske mase, svaka zona je dodatno podijeljena na dvije podzone. Unutar svake zone identificirani
su i opisani setovi diskontinuiteta. Na temelju prikupljenih podataka određene su RMR klasifikacija i GSI
kategorizacija stijenske mase. Kvaliteta stijenske mase s obzirom na RMR klasifikaciju je slaba do povoljna,
a prema GSI kategorizaciji raspadnuta do blokovita. Za sve zone su provedene i kinematičke analize
stabilnosti. Kinematičkim analizama stabilnosti određeni su potencijalni tipovi sloma unutar stijenske mase
(planarni ili klinasti slom, prevrtanje i prevrtanje savijanjem) za svaku inženjerskogeološku zonu. Na temelju
rezultata analiza stabilnosti za svaku zonu je određena podložnost stijenske mase s obzirom na nestabilnost.

Abstract (english)

The aim of this thesis was the determination of the rock mass quality and susceptibility zones related to the
instability of a rock mass outcrop on the ŽC 6055 county road (Oklaj-Kistanje) near Lake Brljan, in
Šibensko-kninska County. Based on the engineering geology mapping of the rock mass outcrop, i.e. on the
homogeneity of its lithological and structural features and orientation change of the road and cut, the rock
mass was divided into 6 engineering geological zones. Because of the different dip and dip directions of the
cut and natural slope of the rock mass, each zone was additionally divided into two subzones. Discontinuity
sets were determined and categorized for each zone, based on which RMR and GSI classifications were
carried out. RMR classification defines the rock mass as poor to fair, while GSI defines the rock mass as
disintegrated to very blocky. Graphic analyses were implemented for each zone and potential types of
instability were determined (planar failure, wedge failure, direct toppling and flexural toppling). The
susceptibility of rock mass was defined for each zone based on the results of the graphic analysis.
