格栅状水泥土搅拌桩挡墙在深圳某软土基坑中的应用

Application of Grid-typed Cement-soil Mixing Pile Retaining Wall in the Soft Soil Foundation Pit in Shenzhen

格栅状水泥土搅拌桩挡墙常应用于基坑深度不大且基坑周边变形控制不严的软土基坑中,文中通过深圳某软土基坑工程实例,结合施工过程及监测数据,分析其施工变形的主要原因,认为该挡墙结构在软土地区基坑中应用是合理的,并提出相关建议,对同行具有一定的参考价值。

The grid-typed cement-siol mixing pile retaining wall is used in the soft-soil pit which is shallow and with loose deformation control.In this paper,an engineering example in Shenzhen is introduced.And the reasons of deformation in the construction stages is analysized.Through analyzing the consturction process and the monitored data,it can be found that this kind of retaining wall applied in the soft soil pit is resonable.Meanwhile,some suggestions of the application process is raised,which can provide the peers of pit engineering with favorable engineering experiences.
