According to the wall deformation monitoring records during the engineering construction of the retaining wall ditch of the Zhenhai Villa in Qingdao,we can find that the soil filling of the retaining wall has caused the passive earth pressure that has already protected the wall.This paper mainly analyzes the relationship between the passive earth pressure and the effective width after the retaining wall being dealt with effectively,which is of great significance for the design,safety evaluation and reinforcement of the retaining wall.%通过对青岛市枕海山庄挡土墙墙前管沟施工期间的墙身变形监测记录的分析研究发现,此挡土墙的墙前填土产生了被动土压力并切实参与工作保护了此挡土墙,因此重点分析了在挡土墙墙前填土经有效处理后,墙前土所能产生的被动土压力与墙前土的有效宽度之间的关系.它的确定对于挡土墙设计以及现状挡土墙的安全性评估及加固具有积极意义.
