Comparative Behavior of Mechanical Response of Earth Retaining Structures with Two Different Material Models

Abstract

Retaining walls are the most commonly adopted solution to retain soils in hilly areas and in case of excavation involved structures like the railways, roadways prone to landslides. The failure of retaining structures and landslides is a major threat to human life and property. The study of soils and the failure criteria has to be understood before recommending a particular slope protection or retention technique. This paper illustrates the study of retaining wall with shelves in dry excavations. The established material models Mohr–Coulomb model (MC) and Hardening Soil (HS) are used. Midas GTS NX software is used for the analysis. The material model is used to analyze the soil behavior considering the parameters like the stiffness, loading, and unloading conditions. Model is studied creating different layers of soils. A comparative study is presented using the two models and using the MIDAS GTS NX Software. The study is basically carried out for the region of Goa and its soil conditions.
