How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article examines modern technologies for the construction of geosynthetic reinforced-soil (GRS) bridge abutments and analyzes their structural features. With the rapid development of transport infrastructure and increasing traffic intensity, there is a growing need for effective engineering solutions that can reduce construction time while maintaining the reliability and durability of bridge structures. One of the promising approaches in this field is the use of reinforced-soil technology, which is formed through layer-by-layer compaction of soil combined with geosynthetic reinforcement elements. The interaction between the soil mass and reinforcing materials significantly improves the stability and load-bearing capacity of the structure. The purpose of this study is to analyze modern technologies for the construction of geosynthetic reinforced-soil bridge abutments and to identify their structural characteristics. To achieve this objective, existing structural schemes of reinforced-soil abutments were analyzed and international experience in their application in bridge construction was reviewed. The paper considers the main types of reinforced-soil abutments used in modern engineering practice, including abutments with separated functions, seat-type abutments, and integral reinforced-soil abutments. For each type, structural characteristics, operational principles, and application areas are examined. Particular attention is given to international experience in the implementation of reinforced-soil technologies in both highway and railway bridge construction, including examples from European countries and Japan. The conducted analysis demonstrates that the use of reinforced-soil technologies allows for a reduction in the volume of reinforced concrete structures, improves construction efficiency, and ensures more uniform structural performance during operation. The results confirm the potential of using reinforced-soil abutments in the construction and reconstruction of transportation infrastructure facilities.
