加筋土挡墙变形特性研究进展

Research progress on deformation characteristics of reinforced soil retaining wall

从理论研究、模型试验、数值模拟和实地调查四方面评述了国内外加筋土挡墙变形特性的研究成果。理论研究方面分析并归纳了研究方法和挡墙变形计算公式;模型试验和数值模拟介绍了已有的静、动力模型试验成果和常用的数值模拟方法。实地调查介绍了现有调查结论及部分规范、标准规定的位移限值。通过4种方式的研究情况介绍,指出了当前加筋土挡墙变形特性研究中存在的一些不足,并进一步阐述了今后的研究方向。

The research achievements on the deformation characteristics of Reinforced Soil Retaining Wall(RSRW),at home and abroad,are summarized from the four aspects,the theoretical research,model test,numerical simulation and field investigation.In the aspect of the theoretical research,the research methods and formulas for calculating the deformation of the RSRW are summarized.In the model tests and numerical simulations,the existing model test results under the static or dynamic conditions and commonly used numerical simulation methods are illustrated.In the field investigation,the existing investigation conclusions and the displacement limits specified by some of the specifications/standards are introduced.Through the introduction of the above four aspects,some shortcomings in the research of the deformation characteristics of the RSRW are pointed out,and future research subjects are put forward.
