提升河道韧性的倒Y形装配式堤岸挡土墙力学特性分析OA

To comprehensively address the challenges associated with enhancing riverbank resilience,including issues such as scouring and erosion of embankments,low foundation bearing capacity,construction timelines,and landscape modifications,this study proposed a novel inverted Y-shaped prefabricated embankment retaining wall.Compared to traditional masonry stone embankments and counterfort retaining walls,the inverted Y-shaped prefabricated embankment retaining wall effectively utilized the boundary conditions of backfill and mound-like structures to control river flow patterns and scouring,while suppressing lateral soil pressure and its eccentric effects.This approach offered advantages in material savings and reduced structural deformation.The stability,overturning resistance,wall-backfill soil pressure,base con-tact stress,lateral displacement,and force transfer path of the structure were analyzed and evaluated through a combination of theoretical cal-culations and numerical simulations.Additionally,the influence of factors such as embankment height ratio,spacing between end columns,and the toe and heel plates was investigated,and recommended value ranges were provided.Finally,the findings were validated and analyzed in the context of a practical engineering case,demonstrating that the inverted Y-shaped prefabricated embankment retaining wall exhibited favorable mechanical properties,contributed to enhancing river resilience,and had promising application prospects.
