Item Comparative Analysis of Calculation Results of Supporting Structure of Soil-Cement Piles(Kaunas University of Technology, Kaunas, 2019) Pshinko, Oleksandr M.; Petrenko, Volodymyr D.; Tiutkin, Oleksii L.; Andrieiev, Volodymyr S.; Hubar, Oleksіy V.; Ihnatenko, Dmytro Yu.; Markul, Ruslan V.ENG: Abstract. The article presents the results of comparison of the stress-strain state of 4 models of a retaining wall structure of soil-cement piles on a landslide-prone slope. This study compares the changes in the stress distribution and displacements in the model elements of the retaining structure of soil-cement piles depending on the design parameters and the method of piles location in the body of the soil mass. The comparison of models of supporting structures of soil-cement piles on a landslide-prone slope allowed obtaining: –the comparative analysis of the quality work of individual elements of the supporting structure for strength and deformation in a three-dimensional representation; –the comparative assessment of the performance of the supporting structure of soil-cement piles on a landslide-prone slope; – histograms of dependences of changes in the angle of piles inclination to the vertical axis of their holding force, strength and deformation of the slope;Item Research of Railway Crashed Stone Use of 40 –70 mm Fraction(Kaunas University of Technology, 2018) Pshinko, Oleksandr M.; Patlasov, Oleksandr M.; Andrieiev, Volodymyr S.; Arbuzov, Maxim; Hubar, Oleksіy V.; Hromova, Olena V.; Marcul, Ruslan V.ENG: The results of the conducted researches on operating, physical and mechanical properties of crushed stone of 40-70 mm fraction are presented in the article as well as the results of the comparison of the given fraction with the fraction of 25-60 mm and determination of the former fraction usage for the ballast with the purpose of more rational fund use during railway repair works. The conducted researches of 40-70 mm fraction of crushed stone allowed receiving: – actual values of technical indices of the product and adopted technical decisions; – conformity of the product with the operating conditions as well as physical and mechanical properties during track maintenance; – ability to perform tests; – comparison of physical, mechanical and operational properties of crushed stone of 40-70 mm fraction with the crushed stone of 25-60 mm fraction.
