Abstract

Vertical anchor plates are commonly employed to counteract lateral pullout forces in structures like sheet pile walls, retaining walls, bulkheads, and abutments for railways and highways etc thereby imparting stability to these structures by restricting the lateral movement. In the present study, the influence of the vertical anchor plate’s aspect ratio, placed in unreinforced and geocell reinforced soil mass have been studied through a series of 3D numerical analysis. It has been observed that the load-carrying capacity of anchor plate is greatly influenced by the aspect ratio of anchor plate. The pullout factor was found to decrease with an increase in L/h up to 5, beyond which decrement was found to be marginal. This indicates that the load-carrying behaviour of the vertical anchor plate shifted from square to strip. Further, the performance of vertical anchor plates significantly increases in the range of 146%-227% with the use of geocell reinforcement for different aspect ratios of an anchor plate. However, the maximum performance improvement was found to be nearly 227% for an aspect ratio (i.e., L/h) of 3, demonstrating that the rectangular anchor plate having an aspect ratio of 3 placed in geocell reinforced soil mass performed better among others.
