大水灰比深搅桩加固技术在浦东机场地下联络道施工中的应用

Application of Reinforcement Technology of Deep Mixing Pile with Big Water-cement Ratio in the Underground Connection Channel of Pudong Airport

摘要:

为解决水泥土深层搅拌法在工程施工中不能满足设计要求这一实际问题，提出大水灰比深搅桩概念。将大水灰比深搅桩用于地基处理，对其进行研究，获得大水灰比下，深搅桩能够按正常进度达到设计要求的深度，并形成稳定的承载力和沉降量的工艺控制规程，为浦东机场深搅桩施工提供施工技术保障。

Abstract:

Big water-cement ratio concept was put forward based on the practical problems in order to meet the design requirements in the construction with deep soil cement mixing method and the stable bearing capacity and settlement amount provided the technical support for deep mixing pile foundation construction in Pudong airport.
