摘　　要：本文对输电线路基础露筋现象进行原因分析,总结了相应的工程预防措施。针对基础露筋范围不确定、露筋区域形状大小不规则、损伤程度难以定性评估等复杂情况,提出了一种基于面积等效的受力计算方法,通过引入安全性指标,推导相关计算公式,根据安全性指标数值大小定量地评估基础露筋损伤对结构受力安全性能的影响,可为实际输电线路工程中基础露筋损伤的评估鉴定和改造加固提供一定的参考。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.
