Abstract

Mechanically stabilised earth (MSE) retaining walls are essential infrastructure elements that provide stability to slopes and support different civil engineering constructions. Nevertheless, the stability and performance of these buildings might be compromised over time due to problems such as heightened loading demands, environmental conditions, and soil qualities. This research aims to improve the stability and performance of MSE retaining walls by using geogrid reinforcement and tieback anchors. Geogrid reinforcement included into MSE retaining walls enhances tensile strength, facilitating contact between the soil and the structure, hence enhancing overall stability. In addition, tieback anchors provide horizontal support, diffusing forces and reducing wall deformation. This work examines the combined impact of geogrid reinforcement and tieback anchors on the performance of MSE retaining walls via an extensive investigation of current literature, laboratory experiments, and numerical analysis. The main goals are to analyse the effects of geogrid location, spacing, and material qualities on the stability of the wall, evaluate how well tieback anchors can withstand lateral earth pressure, and optimise the combination of these strategies to improve overall performance. The laboratory studies will use physical modelling to replicate real-world settings, while numerical modelling will provide valuable insights into the long-term behaviour and performance of the system under different loading scenarios. The project will provide useful information about the design, construction, and maintenance of MSE retaining walls that include geogrid reinforcement and tieback anchors. These integrated solutions provide sustainable and cost-effective methods for managing slope stability and sustaining important infrastructure in civil engineering projects by improving stability, reducing deformation, and boosting load-bearing capacity.
