Abstract The paper presents analytical investigation of bearing capacity of geosynthetic reinforced soil (GRS) bridge abutments with vertical or nearly vertical facing batter angle. A limit analysis (LA) method is proposed using a y-shaped failure mechanism to determine the bearing capacity and the corresponding failure surface geometry within GRS bridge abutments. The proposed method is validated against results from numerical simulations and limit-equilibrium methods. Parametric analyses are subsequently carried out to examine the effects of backfill strength, reinforcement properties, and abutment geometry on the bearing capacity and failure surface geometry of GRS bridge abutments.

GRS桥台承载力及破坏几何的极限分析

摘要 本文介绍了土工合成材料加筋土（GRS）桥台具有垂直或接近垂直的朝向面角的承载力的分析研究。提出了一种极限分析 (LA) 方法，该方法使用 y 形破坏机制来确定 GRS 桥台内的承载力和相应的破坏面几何形状。所提出的方法针对数值模拟和极限平衡方法的结果进行了验证。随后进行参数分析以检查回填强度、加固特性和桥台几何形状对 GRS 桥台承载力和破坏面几何形状的影响。
