| Abstract [eng] |
In the final master's project, technologies of installation of sloping constructions in Lithuania and abroad are analyzed. The survey of sloping structures and their possibilities of use, types of sloping structures and their classification, as well as ways of installing sloping structures are reviewed. The constituents of the concrete mixture used for the installation of sloping constructions and additional materials, researches in this field are presented. In the research section, the influence of the angle of inclination of a sloping plane on the stability of a concrete mix on a sloping plane was studied. Controlling the composition of concrete mix, the composition of the concrete mix used for the installation of a slope over the K29 site was chosen for studies. The magnitude of the coarse aggregate fill in the total aggregate mixture and the effect of the polypropylene fiber on the stability of the concrete mix on the sloping plane and the adhesion of the surface of the formwork panels to the mixture increasing means. The influence of granular and polypropylene fibers on the boundary shear stresses and initial shear stresses of a concrete mix when the inclination angle of the inclined plane is 25 °, 35 ° and 45 ° is determined. |
