Assessment of the Impact of Construction of Reinforced Soil Retaining Walls on Abutment Pile Group Foundation

Abstract

Recently, reinforced soil retaining walls have been increasingly used for construction of abutment pile groups. But those two structures are designed separately from each other, often even by different organisations. The objective of this work was to determine the impact of construction of reinforced soil retaining walls on first-pier pile foundations. The main task was to determine the dependence of the height of the embankment on the growth of adverse effects, the influence of pile length, depth, a possibility to apply nonlinear models and types of installation.Complex modelling in flat and spatial settings has shown the need to consider while designing pile foundations the negative impact of additional horizontal and vertical shifts, as well as of bending moments and longitudinal forces. The study recorded a factor of emergence of negative friction the mechanism of which requires separate study.The main conclusion of the study related to the need to develop a comprehensive assessment of the impact of construction of reinforced soil retaining walls on pile foundations of abutments.
