<p>A novel silo-type field structure has been designed to address the settlement and stability challenges commonly associated with traditional high-fill retaining walls in rugged and elevated terrains. However, the silo-type support components are susceptible to translational block sliding failures, which have the potential to compromise the overall stability of the retaining structure-slope system. In order to mitigate these risks, the system's stability was analysed using upper bound limit analysis and shear strength reduction methods. The results of the case studies demonstrate that the safety factors derived from linear sliding failure mechanisms are in close alignment with those obtained from strength reduction methods, thereby confirming the accuracy of this analytical approach. Improvements in stability can be achieved by enhancing the shear strength of the backfill soil, increasing the number and embedding depth of the cylindrical components, and reducing their self-weight and height-to-width ratio. These findings provide valuable insights for improving overall stability in similar engineering applications.</p>
