软土地基某泵闸深基坑支护失稳分析及处理
摘要:介绍了某泵闸基坑灌注桩围护位移及钢管支撑受力过程,对造成支护失稳原因进行了详细分析,探讨基坑设计及施工工艺存在的问题,介绍了支护失稳后抢险、围护补强、防渗加固及支撑体系补强等措施,同时对加固补强处置效果进行了分析,得出相关结论及建议,为类似基坑顺利施工提供了一定依据。
Abstract:Gates Foundation introduced a pump displacement and steel pile supported retaining the force process, causing instability of the reasons for supporting a detailed analysis, design and construction process of excavation problems, introduced after the emergency shoring unstable, envelope reinforcement, reinforcement and support system impervious reinforcement measures, while disposal of reinforcement reinforcing effects are analyzed, draw relevant conclusions and recommendations for similar pit provided some basis for the smooth construction.
