AB  - U Srbiji je počela izgradnja autoputa E-80 koji će predstavljati saobraćajno čvorište
zapadnog Balkana i biće deo glavne regionalne transportne mreže jugoistočne Evrope. Njegova
ukupna dužina kroz Srbiju iznosi 77 km, a prva deonica u dužini od 5.5 km je završena i puštena u
saobraćaj krajem jula 2023. god. To je prva od četiri deonice Sektora 1 čija je dužina 32.65 km. U
sklopu petlje „Merošina 1“ izgrađen je nadvožnjak koji je oslonjen na devet stubnih mesta na
međusobnom rastojanju od oko 25 m. Svaki stub je fundiran na šipovima i to sa predloženim
rasporedom od 2 šipa u grupi. U radu su na osnovu izvršenih geotehničkih istraživanja terena,
analizirani rezultati nosivosti vertikalno opterećenog šipa prečnika 1.2 m i dužine šipa od L = 18
m. Analiza je izvršena primenom različitih metoda koristeći rezultate statičke penetracije-CPT,
laboratorijskih ispitivanja tla kao i probnog opterećenja šipa.

AB  - Stability analyses were performed for a real engineering-geological cross-section of unsaturated Quaternary silt sediments. Unsaturated shear strength is a function of the two stress variables: net normal stress and matric suction. Constitutive equations (unsaturated shear strength - matric suction) and (angle ∝b - matric suction) were defined for these silty soils. These equations were established on the basis of primary constitutive relationships for unsaturated soils by soil-water characteristic curves (effective degree of saturation - matric suction). Soil-water characteristic curves were obtained from results of experimental tests on draining saturated soil samples under different pressures, performed for the first time in Serbia, in a 15 bar pressure plate extractor, according ASTM. Effective shear strength parameters c' and ∝' were also experimentally obtained from direct shear tests. Stability analyses were performed using the GLE method for different climate conditions, before and after rainfall, i.e. for different values of matric suction. Stability analyses were performed for the same groundwater level, too. It was confirmed that rainfall decreases the angle (pb and stability of natural unsaturated soil slopes. Decreasing the ∝b angle of unsaturated soil, due to rainfall, decreases the safety factor of the slope faster for coarse-grained soil than for finegrained soil.

AB  - Nisu retki primeri vidljivih oštećenja (pukotine i prsline po fasadnim zidovima) na starijim građevinama Beograda koje su fundirane plitko. Najčešće je to posledica neravnomernih sleganja koja često nastaju usled nepredviđenog provlažavanja tla ispod temelja. Ovo provlažavanje je uglavnom lokalnog karaktera i u takvim uslovima je neminovna pojava diferencijalnih sleganja. U ovom radu su izloženi rezultati istraživanja koji ukazuju da pored veličine zone uticaja promene vlažnosti u tlu u horizontalnom pravcu i proračunatih vrednosti sleganja, treba analizirati i ukupnu promenu zapremine tla ispod temelja.
AB  - Examples of visible damage (cracks on the facade walls) on the shallow founded older buildings in Belgrade are not rare. Usually, this is a consequence of unequal settlement resulting from the unexpected moistening of soil under foundation. Moistening usually occurs locally and differential settlement is inevitable in such conditions. This paper presents the research results, which indicate that besides the size of impact zone of moisture change in the soil in horizontal direction and calculated settlement values, total change of soil volume under foundations should be analyzed.
