SOIL-STRUCTURE COMPATIBILITY IN FRAMEWORK FOR FINITE ELEMENT ANALYSIS

For finite element analysis (FEA) to accurately forecast the relationship between soil and structure. A framework for simulating soil-structure compatibility in FEA is shown here. The study looks at how important soil-structure compatibility and affects the accuracy of FEA findings. The overview of different soil-structure interaction models and their limitations. The study proposes a methodology for assessing soilstructure compatibility and its impact on FEA results. The methodology includes the evaluation of the soil-structure interface parameters and their incorporation into the FEA model. That concludes that the consideration of soil-structure compatibility is crucial for accurate FEA results and recommends the incorporation of the proposed methodology in the FEA design process. The behaviour of earth-retaining is significantly influenced by mechanical interactions with the surrounding soil. The inclusion of interface elements between different component materials is typically necessary for the numerical analysis of earth-retaining structures in order to describe soil-structure interactions and capture the transmission of normal and shear stresses via these discontinuities. These components employ a strength/stiffness reduction factor on the soil at the contact. However, using continuum elements to describe soil-structure interactions is the sole choice in some numerical codes or other comparable special interface components are not available. The continuum element technique gives the user more control over the interface characteristics material stiffness and strength, as well as the sizes and forms of the elements at the interfaces. In this article, parameter settings for elements are suggested that will produce numerical results that are identical to those obtained using elements in commercial finite element and finite difference methods.
