Abstract
In the modern era of civilization, the transportation sector plays a pivotal role in a nation’s development. Efficient transportation networks are essential for economic progress, and tunnels are particularly valuable in this regard, as they help reduce travel time and fuel consumption. With growing interest in underground infrastructure, researchers are increasingly focusing on tunnel-related studies. This paper examines the deformational behavior of a horseshoe-shaped tunnel constructed in layered soil, subjected to strip surcharge loads applied at various locations, and influenced by water tables positioned at different depths. The study maintains a constant thickness for each soil layer and utilizes the Mohr-Coulomb model to represent the material behavior. The findings highlight the significant impact of the water table on the tunnel’s deformation, offering valuable insights and encouraging further investigation in this field In addition to these observations, the research emphasizes the relevance of underground construction in modern transportation planning, especially in regions with limited surface space or difficult terrain. Tunnels, by enabling direct routes, not only support faster mobility but also contribute to reducing environmental degradation caused by excessive vehicular emissions. The consideration of layered soil conditions and surcharge loads provides a realistic representation of actual ground conditions encountered during construction. Furthermore, the influence of varying groundwater levels on tunnel deformation underscores the need for integrating hydrogeological studies into geotechnical analysis. By adopting the Mohr-Coulomb model, the study ensures a reliable understanding of soil strength parameters, making the outcomes practical for real-world engineering applications. Overall, the research adds value to the existing body of knowledge, highlighting the importance of comprehensive analysis for ensuring the safety, stability, and efficiency of tunnel structures in the context of sustainable infrastructure development.
