“…Atliekant sankasų stabilumo skaičiavimus negalima vienodai traktuoti geležinkelių ir automobilių kelių sankasų stabilumo dėl skirtingų apkrovų dydžių ir apkrovų pridėjimo vietos. Nepaisant to, kad yra pakankamai daug atliktų tyrimų ir parengtų reglamentų bei taisyklių grunto sankasų stabilumui vertinti, kartais tenka susidurti su sankasų šlaitais, praradusiais stabilumą (Harabinova, 2017;Lu et al, 2020).…”

This paper describes the stability calculations of the most common road embankments slopes and their results using the modified Bishop method. By searching for the smallest possible effective angle of internal friction of the different slope steepness embankments, the possible different bases of the embankment, the weight of the embankment soil, the load caused by transport and the location of load application (shoulder) were evaluated. Analyzing the obtained calculation results, it was determined that at a slope of 1:2 (26.57°) steepness, to ensure slope stability, the calculated effective internal friction angle of the embankment soil should be φʹd ≥ 28.5°, and at a slope of 1:1.75 (29.74°) steepness – φʹd ≥ 29.8°. When the slope is 2:3 (33.69°) steepness, the stability of the slope cannot be guaranteed.

This article is devoted to integral analysis of physicomechanical properties of surface soils peculiar to Akkain, Kok Tobe and Shymbulak landslides of Trans-Ili Alatau located in close vicinity to city borders and in Almaty. While analyzing previous landslides of this region, the authors determined three main reasons of landslide occurrence on these mountain slopes: water saturation of surface subsoils during spring rainfalls, technogenic and gravitational reasons. It has been concluded that in many cases landslides occur due to water saturation of subsoils. It is proposed to consider landslide subsoils as two-phase medium. Algorithm of prediction of reduced physicomechanical properties of two-phase subsoil is summarized. Actual predictions are carried out using the proposed procedure and algorithms. The obtained results for certain types of loose subsoils, such as sandy clay, various loams and clays, are summarized in tables which are required for deep study of landslide occurrence in water saturated subsoils of these slopes on the basis of strain-stress states.

“…However, excavation activities cause modifications in force distribution posing the risk of slope failure [9] . In addition, the presence of water resulting from rainfall and/or human activities leads to the increase of this potential failure [10] due to the loss of shear strength and cohesion properties along the discontinuity planes [11] . Basically, slope instability is controlled by the properties of unfavorable discontinuities with respect to the cut slope orientation [12] .…”

A part of the eastern side of the North Galala plateau is subjected to intense slope stability hazards. The present study aims at assessing and analyzing the different slope failures along the North Galala plateau and predicting the failure types through their kinematic/deterministic and rockfall analyses, followed by the suggestion of mitigation and supporting measures for the unstable zones. The slope rock masses consist of the Paleozoic interbedded rock units of sandstone and claystone at the base and the Cretaceous-Eocene carbonate rock units at the top. Assessment and analysis of rock masses revealed that the studied area shows, planar, wedge, and toppling failures which are controlled mainly by the unfavorable discontinuities. Kinematic analysis of the studied discontinuities with the slope angles and orientations identifies the occurrence of these slope failures through the steeper segments of each slope profile. Deterministic analysis and calculated factor of safety (FS) show that the most studied rock slope discontinuities are stable under both dry static and dynamic condition, and their stability condition is significantly reduced in saturated conditions where the calculated FS is frequently less than unity. Rockfall simulation is constructed at ravelling zones to assess the block trajectories, runout distance, kinetic energy, and bounce profiles of the falling blocks. Supporting and mitigation measures are recommended based on the slope stability analysis, site inspection, and encountered engineering geological conditions of different rock masses.
