| 摘 要： | 分析了粉喷桩在软弱地层中进行基坑支护的优点,并根据工程实例介绍了粉喷桩的设计方法与施工工艺。运用“m”法设计了阶梯形挡土墙,有效地防止了挡土墙的整体滑移和基坑隆起;在搅拌、喷粉的基础上进行了复喷、复搅,提高了挡土墙的支护能力和止水能力。

| Abstract: | This thesis analyzes the advantages of the powder jetting piles for foundation pit retaining support in the soft stratum,and shows the design and construction techniques of the powder jetting piles by field cases.The ladder style retaining wall is designed by "m" method,which prevents the retaining wall from whole slippage and hunching effectively.In the process of construction,the repetition of jetting and mixing are carried out,so the supporting and impermeability of the retaining wall are strengthened. |
