摘　　要：在工程建设中常有混凝土挡土墙,设计人员的疏忽导致挡土墙坍塌造成财损人亡。本文就南京某旧住宅小区九米高混凝土挡土墙出现险情,进行详细分析计算校核。在特定的环境条件和业主要求下,采取‘贴桩加横梁’做法进行加固挡土墙,对加固方法的工作机理和计算模型做了阐述并对加固后挡土墙进行计算分析,工程中有很好的指导意义。In engineering construction,concrete retaining wall is often used,while designers are often careless,which leads to the collapse of retaining wall and even financial damage and death.In this paper,a nine-meter high concrete retaining wall with danger in a residential area in Nanjing is analyzed,calculated and checked in detail.Under the specific environmental conditions and the owner's requirements,the retaining wall with danger is reinforced by"sticking piles and beams".The working mechanism and calculation model of the reinforcement method are described,and the calculation and analysis of the reinforced retaining wall are carried out,which has a good guiding significance in the project.
