摘　　要：在黄土地区建造超高层建筑时,由于地质条件的限制,钻孔灌注桩成为一种常用的基础工程技术。与其他区域相比,黄土地区常采取泥浆护壁的钻孔灌注桩施工技术。钻孔灌注桩的设计需要考虑施工工艺技术以及土层的物理力学参数、承载力和变形特性,以确保建筑物稳定和安全。结合工程实例对超高层建筑下钻孔灌注桩的压缩变形及沉降进行初步分析。Drilled pile foundation has become a common foundation engineering technology in building super high-rise buildings in the loess area due to geological conditions limitation.Compared with other regions,the drilling and grouting pile construction technology with slurry wall protection is often used in loess area.The design of drilled piles needs to consider the technical process of construction and the physical and mechanical p arameters,bearing capacity,and deformation characteristics of the soil layer to ensure the stability and safety of the building.This paper combines engineering examples to conduct preliminary analysis on the compression deformation and settlement of drilled piles in the foundation of super high-rise buildings.
