Application and Performance Analysis of Composite Support of Anchor Cable and SMW Work Pile in Deep Foundation Pit Project

为了解决水利工程中泵站深基坑的支护问题,研究提出一种结合锚索和SMW工法桩的复合支护技术,并对其应用和性能进行分析。结果表明,广东某拟建的水利泵站深基坑项目应用中,复合支护结构在整体稳定性和抗倾覆稳定性方面的验算结果分别为1.379和2.026,符合设计要求。尽管锚索应力的模拟数据与实际情况存在一定偏差,但整体变化趋势相似。此外,桩身水平位移和周边地表沉降的监测结果与模拟数据基本一致。研究显示,结合锚索和SMW工法桩的支护方案在水利工程泵站建设具有良好的应用效果和性能,可为泵站建设工程的设计和施工提供技术支持。

To solve the support problem of deep foundation pits in water conservancy engineering,a composite support technology combining anchor cables and SMW construction piles was proposed,and its application and performance were analyzed.In the application of a proposed water conservancy pumping station deep foundation pit project in Guangdong,the verification results of the composite support structure in terms of overall stability and anti overturning stability are 1.379 and 2.026,respectively,which meet the design requirements.Although there is some deviation between the simulated data of anchor cable stress and the actual situation,the overall trend of change is similar.In addition,the monitoring results of the horizontal displacement of the pile body and surrounding surface settlement are basically consistent with the simulated data.Research has shown that the support scheme combining anchor cables and SMW construction piles has good application effects and performance in the construction of hydraulic engineering pump stations,providing technical support for the design and construction of pump station construction projects.
