Abstract - In this study, the influence of soil-structure
The first three failure modes are the most frequently encountered, so during the design process, the wall’s geometry is evaluated against criteria for sliding, overturning, and bearing capacity. Additionally, the wall’s cross-section is assessed to ensure the materials used can handle the applied stresses. Of these failure modes, sliding is often the most critical to address, as it typically dictates a larger base area for stability—often resulting in a design that is structurally conservative or under-stressed.
interaction on a counterfort retaining wall was explored using the finite element software ANSYS 18.0. The wall was modeled as being fully supported by and surrounded by soil, replicating natural ground conditions. To accurately reflect real-life scenarios, a sufficient portion of soil beneath and around the wall was included in the model. The analysis focused on static loading conditions. Various heights and shapes of the counterfort retaining wall were examined to assess how these changes affect stress distribution and structural deformation, revealing notable differences in performance.

1. INTRODUCTION A retaining wall is a structure built to hold back soil and maintain different ground levels on either side. The soil or material held behind the wall is referred to as backfill, and the wall is specifically constructed to support this load. Retaining walls are widely used in civil engineering projects such as railways, highways, bridges, canals, and other works where it's necessary to hold back earth on one side. There are several types of retaining walls, including cantilever (or T-shaped), semi-counterfort, and counterfort walls. Other less common variations include buttress walls and braced walls. Among these, the counterfort retaining wall is particularly popular due to its relatively straightforward construction process.

Typically, counterfort retaining walls are built using plain cement concrete, although stone or brick masonry may also be used in certain cases. However, these walls can be vulnerable to various types of failure, such as: 1.

Researchers have extensively analyzed various structures using the concept of soil-structure interaction. Many studies have particularly focused on soil-structure interaction in relation to retaining walls. However, the interaction between soil and Counterfort Retaining Walls, especially with varying geometrical and geotechnical parameters, remains largely unexplored. Identifying this gap in research, the present study is formulated to investigate the behavior of Counterfort Retaining Walls under the influence of soil-structure interaction, considering different geometrical and geotechnical factors.
