AB  - U radu su prikazani rezultati geotehničkih istraživanja za potrebe izgradnje visećeg pešačkog mosta preko klisure reke Đetinje u Užicu. Predviđeno je da most, sistema prednapregnute trake, omogući prelaz pešacima sa desne dolinske strane na stranu Starog grada, koja je opasana strmom liticom (cca. 40 m visine). Za potrebe formiranja geotehničkog modela i strukturnog sklopa krečnjačke stenske mase korišćen je postupak fotogrametrijskog snimanja dronom. Predviđeno je da se zatežuća sila (od oko 30 MN), koju most prenosi na obalni stub, prihvati i prenese na stensku masu sistemom prednapregnutih ankera. U tom pogledu izvršena su ispitivanja nosivosti dva sidra, koja su ugrađena u subhorizontalne bušotine. Rezultati numeričkih analiza i uspešan test nosivosti sidara pokazuju da je stenska masa u stanju da izdrži sile zatezanja od mostovske konstrukcije. Pomeranja obalnog stuba su nekoliko mm u slučaju pretpostavke o kontinualnoj stenskoj masi. Kada se eksplicitno u analizu uvedu pukotine pomeranja su oko 6 cm. Ovi rezultati se morju verifikovati kroz odgovarajući monitoring tokom izgradnje mosta.
AB  - This study shows the results of geotechnical investigations performed for the construction of pedestrian suspension bridge, crossing the Đetinja river in the town of Užice. The prestressed ribbon type bridge should connect the right bank of the river with the the vertical cliff (approx. 40 m high) where the Old town is located. Geotechnical model of the limestone rock mass and joint network model are formed by utilization of drone photogrammetry. The tensile force (approx. 30 MN) induced on the bridge pillar should be accepted and transfered to the rock mass by the system of prestressed anchors. Two investigation test were performed on anchors installed in sub-horizontal boreholes. Successful anchor load test and numerical analysis showed that the rock mass is capable of sustaining tensile force induced by the bridge structure. Displacements of the bridge abutment are approx. several mm for an assumption of isotropic rock mass behaviour. If joints are applied explicitly the displacements are in the order of 6 cm. These findings have to be confirmed by monitoring during the construction stage.

AB  - In this article, we are elaborating an example of predictive rockfall assessment by
using Terrestrial Laser Scanning (TLS) in monitoring a road cut, hosted in flysch rock formation,
near Ljig in Serbia. A sequence of rockfall events from 2013-2019 is presented, while the cut
has been more broadly investigated in our earlier work. Beside occasional rockfalls which are
routinely detected by annual TLS monitoring, it was possible to track the pre-failure
deformations preceding a series of rockfalls, reaching 0.3 m3 in volume with 0.5 annual
reoccurrence probability. Monitoring enabled identification of subtle displacements of about 1
cm after the first event in 2014 and keeping track of its progression. After a series of events in
the following years, we were able to define the pre-failure threshold which can be applied to the
adjacent rock blocks, assuming a similar block volume. It also enabled us to anticipate and
simulate the event before it happens. This approach allows planning, prevention and protection,
and there is a great deal of interest to standardize it for high-risk slopes and cuts in rock masses.

AB  - The section of E75 motorway under construction was subjected to simulation of potential rockfall hazard. 3D point-cloud surface model of the rock slope, obtained by a combination of LiDAR and UAV techniques, was used for mapping of discontinuities, their orientation and spacing. These were inputs for appropriate slope stability analyses, which were further used do delineate potential depletion zones or rockfall block sources. Once delineated, source zones were used to simulate 3D rock trajectories over 3D surface slope model, for various block sizes. All trajectories were compared and evaluated for their potential impact on the viaduct setting, based on their spatial propagation, kinetic energies and forces, bouncing heights etc. Finally, according preventive measures for rockfall hazard mitigation were proposed.

AB  - This paper presents the results of uniaxial compression strength tests performed on samples composed of sandstone and siltstone discs. Samples are loaded until failure, with the aim of determining the dependency between uniaxial compressive strength and the volumetric percentage of siltstone. In order to precisely determine the moment and mechanism of failure of each composite sample, the process was recorded with a high-speed camera (120 fps). Uniaxial compressive strength decreases exponentially with an increase of siltstone volumetric participation. The critical ratio at which the uniaxial compressive strength of the composite sample equals the strength of the uniform siltstone sample was obtained at a siltstone percentage of 60%. The failure mechanism is highly dependent on the siltstone percentage, and occurs as shear or tensile failure, or combined shear-tensile failure in individual discs or throughout the entire composite sample. Comparison of the obtained exponential equation with empirical suggestions shows a good correspondence. It is suspected that the disagreement between the particular conclusions of this study and conclusions of other laboratory studies is due mainly to sample micro-heterogeneity.

Discontinuity data was collected and the geological strength index (GSI) value was determined immediately after excavation based on the quantified GSI chart. Slake durability tests were performed up to the fifth cycle. Samples were exposed to natural climatic conditions during a twelve-month period, in order to quantify slaking process by means of disintegration ratio. As a consequence of exposure, samples disintegrated into smaller fragments. On these bases, the model aimed at addressing delayed failure of cuts is proposed in the paper.
