摘　　要：振动沉管灌注桩因其承载力高,稳定性好,沉降量小等优点而被广泛应用于各种建筑工程,目前各种规范和图集中振动沉管灌注桩最大直径为600 mm。通过在湿陷性黄土建筑场地设计采用850 mm大直径振动沉管灌注桩工程实例,介绍湿陷性黄土建筑场地大直径振动沉管灌注桩的特点,分析了大直径振动沉管灌注桩管可行性,介绍了其设计、施工及检测的相关内容,并与其他桩型进行经济效益对比分析。Vibrating sinking piles are widely used in various construction projects due to their high bearing capacity, good stability and small settlement. At present, the maximum diameter of vibrating sinking piles in various specifications and drawings is 600mm. By designing a 850mm large-diameter vibrating sinking cast-in-place pile in the collapsible loess construction site, the characteristics of the large-diameter vibrating sinking pile in the collapsible loess construction site are introduced, and the large-diameter vibrating sinking pile is feasible. Sexuality, introduced the relevant content of its design, construction and testing, and compared the economic benefits with other pile types.
