| 摘 要： | 挡土墙病害和破坏形式主要有:滑移、倾覆、墙身开裂等,并且主要考虑一级或单级挡墙的破坏。本文通过对东莞南城区能源厂重叠式组合挡土墙失稳观察,提出其破坏形式除了一般挡土墙具有的常见病害倾覆之外,还伴随有该类挡土墙特有的灾害流土的发生,本文从定量、定性两方面对该失稳挡墙进行了具体分析,最后,根据分析结果对该挡墙提出了具有针对性的处理措施。通过对该挡土墙的分析总结,为今后该类挡土墙的设计、施工提出了极具借鉴价值的建议。

| Abstract: | Slipping,turnover,dehiscence etc.are primary failure modes of retaining walls.Usually,only one or single stage retaining wall failure was considered.This paper presents a failure by groundwater piping through overlapping compound retaining walls besides those damages mentioned above at a power generation plant in the south of Dongguan city.Authors analyze quantitatively and qualitatively the instability of retaining walls and recommend appropriate measures for treatment of failure of retaining walls. |

| Keywords: | Overlapping compound retaining walls Turnover Failure by piping |
