以返包式加筋土挡墙为研究对象，提出了面板位移的计算方法。将面板水平位移分为两部分计算：筋材应变引起的水平位移、加筋区在其背部水平土压力作用产生的整体水平位移。计算筋材应变引起的水平位移时，通过潜在破坏面、自然休止角将筋材分段计算，并假定筋材内力的水平分布，得到筋材应变引起的水平位移的简化计算模型。计算加筋区整体水平位移时，将加筋区等效为“悬臂梁”进行计算，考虑了加筋区弹性模量随高度的变化。本文的理论方法估算值与试验、数值模拟结果进行了对比，结果显示：二者分布趋势基本一致，能够较好地计算返包式加筋土挡墙的面板位移。

The study focused on wrap-around reinforced soil retaining walls and proposed a calculation method for panel displacement. The horizontal displacement was divided into two components for calculation: the horizontal displacement caused by the strain of reinforcement and the overall horizontal displacement generated by the horizontal earth pressure acting on the back of the reinforced zone. When calculating the horizontal displacement caused by the reinforcement strain, the reinforced zone was divided into subzones through the potential failure surface of reinforced soil retaining wall and the natural repose angle of soil. The horizontal distribution of the reinforcement load was assumed, yielding a simplified calculation model for the horizontal displacement caused by reinforcement strain. For the calculation of the overall horizontal displacement of the reinforced zone, the zone was treated as a ' cantilever beam', taking into account the variation in elastic modulus of the reinforced zone with height. The theoretical results obtained through the proposed method were compared with experimental and numerical simulation results. The distribution trend of the displacements was basically consistent, indicating that the proposed method can effectively calculate the panel displacement of wrap-faced reinforced soil retaining walls.
