Modelación numérica usando elementos finitos en 2 dimensiones para optimizar el diseño de muros anclados frente al método tradicional

Abstract

The present paper analyzes the design of an anchored wall using simplified thrust theory, often referred to as "the traditional method." Recognizing the potential for enhancement through 2D finite element numerical modeling, both approaches were applied under identical conditions and soil characteristics. This allowed for a comparative review of the designs generated by each method. The study demonstrated improvements in slope stability compared to natural soil conditions. Additionally, comparisons were made in terms of anchor geometry, adherence to Eurocode standards for anchor design, stress distribution diagrams, and variations in stress due to excavation progress and deformations in the anchored wall caused by soil conditions. It is noteworthy that the modeling included both passive and active anchors. The results enabled a comprehensive comparison, highlighting changes and improvements. Furthermore, an economic analysis was conducted using APUS to illustrate the economic impacts of the construction modifications.
