中文摘要:本文通过大量查阅双排桩在基坑支护中的理论和应用等方面的研究,以武汉某深基坑支护为研究背景,通过设置前长后短非等长双排桩进行基坑支护,并利用武汉天汉设计软件对该项目的某一个支护段进行设计计算研究,计算结果表明:该支护段的前后排桩的最大位移为37.9mm在地面以下1.0m处(即桩顶),被动区弹性抗力安全系数=3.90。而在本项目基坑中的预警控制指标为支护结构水平位移≤40mm,能够满足设计监测要求,为以后非等长双排桩在基坑中的应用提供参考借鉴。

Application of non-equal length double-row piles in a project in Wuhan
Abstract:In this paper, through extensive research on the theory and application of double-row piles in foundation pit support, a deep foundation pit support in Wuhan is taken as the research background, and the foundation pits are set by setting the front long and short non-equal length double-row piles. Protected and used Wuhan Tianhan design software to carry out design calculation research on a certain supporting section of the project. The calculation results show that the maximum displacement of the front and rear row piles of the supporting section is 37.9mm at 1.0m below the ground (pile top), the passive zone elastic resistance safety factor = 3.90. The early warning control index in the foundation pit of the project is that the horizontal displacement of the supporting structure is no more than 40mm, which can meet the design monitoring requirements, and provide reference for the application of non-equal length double-row piles in the foundation pit.
