Abstract

The pier is a critical component of bridge structures, and its load-bearing capacity directly impacts the safe operation of the bridge. However, during its service life, piers are susceptible to various structural defects that degrade their load-bearing capacity. To systematically investigate the influence of these defects on pier performance, this study employs Abaqus finite element analysis (FEA) to focus on the safety and durability issues arising from pier damage. To effectively evaluate the residual bearing capacity of bridges, a numerical simulation method is adopted to establish assessment models for piers with varying spalling locations and areas. Predicted values of residual vertical load-bearing capacity under different damage levels are calculated. The results indicate that spalling area significantly affects pile foundation capacity, highlighting the necessity for timely pier inspection. The residual bearing capacity evaluation method, based on pier spalling location and area, provides a reliable approach to assess pile foundation capacity and offers robust support for bridge safety management and maintenance decision-making.
