大直径深层旋喷搅拌桩在昊胜大厦深基坑支护工程中的应用

Application of Large-diameter Deep Mixing Pile in the Haosheng Building Foundation Ditch Engineering

摘要:

大直径深层旋喷搅拌桩具有强度高、变形小、防渗透性好的优点，在地基加固和止水帷幕工程中得到推广应用。以深厚砂层赋存丰富地下水区域深基坑工程为例，通过设计方案和工程施工以及结合基坑监测结果，充分证实大直径深层旋喷搅拌桩所发挥的优良止水作用，值得推广。

Abstract:

The large diameter deep mixing pile has the advantages of high strength, small deformation and good anti-permeability. It is widely used in areas of foundation strengthening and water-sealing engineering. Based on the deep foundation ditch engineering in abundant groundwater region, the water-sealing function with large diameter deep mixing pile was proved by the combination of design program, engineering construction and the excavation monitoring result.
