东莞南城区能源厂组合式挡土墙失稳分析及处理措施

INSTABILITY ANALYSIS OF RETAINING WALLS AND THEIR TREATMENT AT A POWER GENERATION PLANT IN THE SOUTH OF DONGGUAN CITY

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。

Slipping, turnover, dehiscence etc. are primary failure modes ot 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 Dongguan city. Authors analyze quantitatively and qualitatively the instability of retaining walls propriate measures for treatment of failure of retaining walls. plant in the south of and recommend appropriate measures for treatment of failure of retaining walls.
