摘　　要：对既有挡墙基础下软弱土层进行注浆加固,能够提高地基承载力、减少软弱土层长期固结对挡墙的影响。重力式浆砌毛石挡墙属于砌体结构,其结构特性决定了其整体性不佳,若注浆方法不当将会对挡墙结构产生不利影响。通过实际案例中的事前优化设计计算、注浆过程沉降观测、项目完成后对数据分析总结,研究了注浆对既有砌体构筑物的影响,总结了相关规律。Grouting and reinforcement of the soft soil layer under the existing retaining wall foundation can improve the bearing capacity of the foundation and reduce the impact of long-term consolidation of the soft soil layer on the retaining wall.The gravity type slurry masonry retaining wall belongs to the masonry structure,and its structural characteristics determine its poor integrity,such as improper grouting method will adversely affect the structure of the retaining wall itself.Through the optimization design calculation in the actual case,the displacement observation during the grouting process,and the analysis and summary of the data after the completion of the project,the influence of grouting on the existing masonry structures was studied,and the relevant laws were summarized.
