This article analyzes the causes of exposed reinforcement in transmission line foundations and summarizes corresponding engineering prevention measures.To address challenges such as uncertain reinforce-ment range,irregular shape and size,and difficulty in qualitative assessing damage,a numerical calculation method based on area equivalence is proposed in this paper.By introducing the safety index,the relevant calcu-lation formula is derived,which can quantitatively evaluate the impact of the foundation exposed reinforcement damage on the structural safety performance.This study serves as valuable references for assessing,identifying,and retrofitting foundation exposed reinforcement damage in transmission line projects.
