文章以实际工程为例，从加固理论、支护结构选型、施工工艺选择、加固应用效果等多方面阐述了单轴双向水泥土搅拌桩在软土地区基坑被动区的加固应用。工程效果表明，单轴双向搅拌工艺在软土地区成桩效果良好，采用水泥土搅拌桩进行坑内土加固后，在改善基坑结构稳定安全的基础上，能够有效控制支护结构的桩顶位移，可为软土地区类似工程基坑支护设计提供参考。

This article takes practical engineering as an example to illustrate the reinforcement application of single-axis bidirectional cement soil mixing piles in the passive zone of foundation pits in soft soil areas from multiple aspects such as reinforcement theory,support structure selection,construction process selection,and reinforcement application effects.The engineering effect shows that the single axis bidirectional mixing process has good pile forming effect in soft soil areas.After using cement soil mixing piles for soil reinforcement in the pit,the pile top displacement of the support structure can be effectively controlled on the basis of improving the stability and safety of the foundation pit structure.It can provide reference for the design of similar engineering foundation pit support in soft soil areas.
