THE INFLUENCE OF GEOSYNTHETIC MATERIALS ON THE RESISTANCE OF REIN-FORCED SOIL WALLS TO HORIZONTAL MOVEMENTS

Abstract

The article deals with the construction of reinforced soil walls using various types of reinforcing elements. It was determined that geosynthetic materials are more resistant to moisture and aggressive environments, but they are sensitive to temperature changes and have the ability to deform under load. One of the mechanisms of the destruction of reinforced soil walls is related to the insufficient length of the reinforcing element. The analysis of research showed that depending on the properties of geosynthetic materials, the size of the displacement distribution also changes. They can be accompanied by the formation of cracks at the top of the separation wall and uneven horizontal movements of the front part of the reinforced soil wall. The work analyzed the results of the deformation assessment depending on the physical and mechanical characteristics of the materials used in the construction of reinforced soil walls, which showed that the angle of internal friction of the aggregate soil and the axial stiffness of the geosynthetic material have the greatest influence on the amount of horizontal movements of the front part. The use of geogrids with elliptically shaped cells in the construction of reinforced soil walls has a significant effect on the amount of suction stress.
