关于加筋土挡墙中,筋材与墙后填土的综合效应和面板刚度对加筋土挡墙的稳定性影响尚未得到充分研究,加筋土的现行设计方法也存在诸多待完善的地方。通过改变加筋土挡墙的面板刚度(厚度),实施了整体式面板加筋土挡墙在荷载作用下的室内模型实验,以研究面板刚度对加筋土挡墙稳定性能的影响。实验结果表明:整体式加筋土挡墙在水平荷载的作用下,随着面板刚度的增加,挡墙的稳定性能越好,整体变形越小;整体式加筋土挡墙面板在荷载作用下的变形较均匀,未出现突变变形;挡墙的面板刚度在加筋土挡墙的结构设计中占有重要地位。可为加筋土挡墙结构设计和解决实际工程问题提供实验基础和依据。
With regard to the reinforced earth retaining wall, the comprehensive effect of the reinforcement and the backfill of the wall and the stiffness of the panel on the stability of the reinforced earth retaining wall have not been fully studied, and there are still many places to be improved in the current design methods of the reinforced earth . By changing the panel stiffness (thickness) of the reinforced earth retaining wall, an indoor model experiment of the integrated panel reinforced earth retaining wall under load was carried out to study the influence of panel stiffness on the stability of the reinforced earth retaining wall. The experimental results show that with the increase of panel stiffness, the stability of retaining wall is better and the overall deformation is smaller under the action of horizontal load. The integral reinforced retaining wall under load The deformation of the retaining wall does not appear sudden deformation. The rigidity of the retaining wall plays an important role in the structural design of the retaining wall. It can provide experimental basis and basis for the design of reinforced earth retaining wall structure and solving practical engineering problems.
