Application Research of Foundation Pit with Deep Mixing Pile and Double-row Pile

以一实际基坑支护工程为研究背景,该基坑工程的支护形式为双排桩结合深层搅拌桩,分析了现场监测资料如基坑变形、桩体变形等。结果表明,这种支护形式能够确保基坑的稳定性。最后以实测数据为依据,运用数值模拟软件对这种支护形式进行模拟实验,分析了深层搅拌桩和双排桩联合支护结构的变形特征和受力机理,并且对深层搅拌桩及双排桩的位置关系进行了探讨。本文的实例分析可以为类似工程提供必要的参考。

A practical pit support engineering is taken as research background,the engineering support form is the double-row piles combined with deep mixing piles.The field monitoring data such as pit deformation,deformation of the pile are analyzed.The results show that the supporting form can ensure the stability of the pit.On the basis of measured data,the numerical simulation is used to analysis of the deformation and stress mechanism of deep mixing pile and double-row piles joint support structure,and the location of deep mixing pile and double-row pile is discussed.The analysis of this paper can provide the necessary reference for similar projects.
