摘　　要：本文通过对产生裂缝的既有扶壁式挡墙现场检测与计算分析研究,探讨裂缝对结构稳定性的影响,并进一步评估挡墙的安全性。既有挡墙出现病害现象时,应对挡墙结构性能、墙后填土进行检测,通过整体性稳定计算,结合监测数据等进行综合评判。评估结果表明,一般及地震工况下挡墙的稳定性和地基承载力符合设计要求,主要受力构件满足设计要求,但部分配筋未达要求,综合各参数最终判断挡墙可以继续安全“服役”。The paper investigates the impact of cracks on the structural stability of a buttress retaining wall through field inspections and computational analysis,and further assesses the wall s safety.When a retaining wall exhibits signs of damage,it’s essential to inspect the structural performance of the wall and the backfill soil.Comprehensive evaluation should be conducted through overall stability calculations,combined with monitoring data and other factors.The assessment results indicate that the stability and foundation bearing capacity of the wall under normal and seismic conditions meet design requirements.The primary load-bearing components satisfy design standards;however,some reinforcement doesn’t meet the specified requirements.Considering all parameters,the final judgment is that the retaining wall can continue to safely"serve."This study provides theoretical guidance for the safety analysis and assessment of retaining walls.
