摘要

采用有限元-近场动力学耦合方法，分析公路路基悬臂式挡土墙的变形破损；在结构破损的较小区域采用近场动力学离散，实现了挡土墙整体和局部变形破损的全过程模拟。以某路基悬臂式L型挡土墙为例，进行全过程精确模拟。结果表明：（1）墙体处于绕墙底转动模式，墙体以承受水平荷载为主，为受弯构件；（2）在L型转折交叉内侧处有较大的拉应力出现，最终形成了约6 cm的裂缝，破损处有明显的应力集中和应力重分布发生；（3）在同等计算条件下，扶壁式挡土墙拉应力降低了80%，没有出现裂缝。因此，增加扶壁是改善挡土墙受力条件、防止发生破损的有效措施。

Abstract

In this study， damage analysis of a subgrade cantilever retaining wall was conducted based on the FEM-Peridynamics coupling method. In this method， only the damage zone is required to be discretized into Peridynamics particles such that the overall structure and the local failure can be simulated simultaneously from the intact to the complete failure states. Numerical examples about an L-shape cantilever retaining wall is thoroughly simulated. The analysis results demonstrate that：（1） the cantilever wall rotates along its bottom. The wall is mainly subjected to the horizontal loadings and it belongs to a bending member. （2） a large tension stress occurs in the internal turn point of the L-shape， which results in a 6 cm-long crack. Stress concentrations and stress redistributions appear in the damage zone evidently. （3） under the same conditions， the counterfort retaining wall has a small tension stress， i.e.， it decreases by 80% compared with the subgrade cantilever retaining wall. In this case， no crack occurs. Therefore， designing a counterfort is one of effective measures to ameliorate the loading condition and to prevent cracks of the retaining wall.
