Abstract: This research investigates the behaviour of slopes during road construction on sloping terrains with a focus on the influence of water table variations and the effectiveness of soil nailing as a slope stabilization technique. The PLAXIS software is utilized to simulate the geotechnical aspects of the slope and analyse its stability and deformation under different water table conditions, both with and without the implementation of soil nailing. The study includes site investigation and data collection, conceptualization of the slope model, construction sequence simulation, and analysis of results.

The simulation results demonstrate that elevated water tables lead to reduced slope stability, increased settlements, and horizontal displacements. However, the implementation of soil nailing shows promising results in improving slope stability and reducing deformations. The findings provide essential insights for the design and construction of road infrastructure in hilly areas with varying water table conditions. The research highlights the significance of considering soil nailing as a viable slope stabilization technique in mitigating the impact of water table fluctuations. It contributes to the development of design guidelines and recommendations that incorporate soil nailing for ensuring the safety and longevity of road projects in such terrains. However, the practical application of these guidelines requires consideration of site-specific factors and engineering expertise.
