Abstract

Abstract: Taking the reinforced earth retaining wall panel as the research object, the model experiment of reinforced earth retaining wall was carried out by changing the structure form of the reinforced earth retaining wall panel (panel structure, panel stiffness), and the effect of different panel structure forms on the deformation performance of reinforced earth retaining wall was discussed. The results show that under the action of external loads, the deformation of the reinforced earth retaining wall panel shows an inverted triangular distribution;the reinforced soil retaining wall with composite panel bears higher load capacity and has better ability to adapt to deformation.Panel type plays an important role in the study of the deformation performance of reinforced earth retaining wall.The research results can provide some foundation and basis for the application of practical engineering.

Key words: highway engineering, reinforced earth retaining wall;deformation performance;panel structure form, model experiment

摘要： 以加筋土挡墙面板为研究对象，通过改变挡墙面板的结构形式（面板结构、面板刚度）对加筋土挡墙进行了模型实验，探讨了不同面板结构形式对加筋土挡墙变形性能的影响。研究结果表明：在外荷载作用下，加筋土挡墙面板的变形呈上大、下小分布；复合式挡墙承受荷载能力和适应变形能力最强。面板类型在加筋土挡墙变形性能研究中占有较为重要的地位，研究成果可为实际工程的应用提供一定的基础和依据。
