The motivation and scope of the present work are to investigate the interaction phenomenon of two closely spaced square plate anchors through physical modelling and validating it with the help of finite-element modelling. In the present study, different sizes of plate anchors are considered for studying their uplift behaviour when they are laid as single as well as in a group of two symmetrical anchors. A large-scale model testing facility has been developed and fabricated in order to perform the physical modelling. In physical modelling, poorly graded, dry Quartzanium sand is utilized as the foundation material. PLAXIS^3D, a finite-element software for geotechnical engineering, has been used to validate the experimental results obtained from the large-scale model testing facility. The effects of embedment depth and size of the anchor plate as well as layering in soil media are the parameters considered in order to determine the interaction factors with respect to the uplift capacity and displacement of anchors.

本工作的动机和范围是通过物理建模研究两个间距很小的方形板锚的相互作用现象，并借助有限元建模对其进行验证。在目前的研究中，考虑将不同尺寸的板式锚固器放置为单个或成组的两个对称锚固器，以研究其举升行为。为了进行物理建模，已经开发并制造了大型模型测试设备。在物理建模中，使用坡度较差的干四方沙砂作为基础材料。PLAXIS ^3D，一种用于岩土工程的有限元软件，已用于验证从大型模型测试设施获得的实验结果。考虑到锚固深度和锚固板的尺寸以及在土壤介质中的分层的影响，这些参数是确定与锚固力和位移有关的相互作用因素的参数。
