采用CFG桩复合地基的软土基坑施工探讨

CFG桩地基处理可有效提高土体强度,造价相对低廉,常用作道路路基、建(构)筑物基础等主要承受竖向荷载的场所,因其桩身的抗弯剪强度低,在施工过程中承受稍大的拉力、水平推力会造成桩基损坏。该文就先施工CFG桩再进行基坑开挖的软土基坑施工问题进行了讨论和总结。

Discussion on Construction of Soft Soil Pit for Compound Subgrade with CFG Pile

The treatment of subgrade with CFG pile can enhance the soil strength.Its construction cost is relatively low and cheap.It is often used as the roadbed,the building (structure) foundation and so on mainly bearing the vertical load.The larger pulling force and the horizontal thrust borne in the course of construction will cause the damage of pile foundation because of low bending shearing strength.The article discusses and sums up the construction issues of soft soil pit by the construction of CFG pile first...
