摘要
以加筋土挡墙楔体破坏模式为基础 ,将墙面板等效为弹性地基梁 ,提出了加筋土挡墙侧向变形分析的力学模型 ,进而研究了变形的影响参数。实测数据表明该模型具有较高的预测精度。
A model for calculating the lateral displacement for a reinforced soil retaining wall is proposed in the paper. The retaining wall panel is assumed as an elastic?foundation beam in the new model, and it is based on the Coulomb failure wedge assumption. The relation between the lateral displacement and related parameters is studied. It has shown that the displacement performance of a reinforced soil retaining wall can be well described by the model. The theoretical prediction of the model is compared with that of the numerical results and observed data. It has shown that the prediction has a high precision. The model, really, is more efficiency than that of the numerical analysis.
