摘　　要：多支点排桩支护结构受力明确,在黄土深基坑中得到了广泛应用,但对其工作机理和计算方法目前仍有待进一步完善,开展多支点排桩的分析计算研究具有重要理论和工程实际价值。基于某地铁黄土基坑,采用不同计算方法对多支点排桩支护体系进行了对比分析,并与实测结果进行了对比,探讨了各计算方法对黄土深基坑支护的适用性,提出了合理的分析计算方法,可为类似案例提供借鉴和参考。The supporting structure of multi support piles has been widely used in loess deep foundation pit,but its working mechanism and calculation method still need to be further improved.It has important theoretical and practical value to carry out the analysis and calculation of multi support piles.In this paper,based on a subway loess foundation pit,different calculation methods are used to compare and analyze the multi support pile row support system,and compared with the measured results,the applicability of each calculation method to the loess deep foundation pit support is discussed,and reasonable analysis and calculation methods are proposed,which can provide reference for similar cases.
