Application and analysis of reinforcement effect of soil between double-row piles in deep foundation pits located in 1st terrace near Yangtze River

  • 摘要: 简化双排桩桩间土加固体为实体杆单元,采用水平向的桩土作用弹簧与前后排支护桩相连接,考虑其抗剪及抗弯能力,在双排桩桩土相互作用计算模型的基础上,提出了计算前后排桩间土加固作用对支护结构内力及变形影响的方法。结合武汉市长江一级阶地基坑工程实例,将计算结果与实测值进行对比分析,以验证该计算方法的可行性与实用性,以期为同类型基坑支护设计提供有益参考。
    Abstract: The cement-stabilized soil is simplified as bar element, and it is connected with double-row piles by a series of horizontal rings. Besides, the bearing moment and shear of cement-stabilized soil are considered too. Based on the model considering the pile-soil interaction of double-row piles, a method for calculating forces and deformation of supporting structure is proposed. In order to verify the correctness and practicality of the proposed method and to provide a useful reference for the design of similar excavations, the calculated result are compared with the observated data in specific deep foundation pits located in 1st terrace near Yangtze River in Wuhan City.
