摘　　要：通过分析湿陷性黄土场地上挤密地基的浸水试验结果,探讨了沉管挤密桩地基处理的深度问题,建议在处理大厚度湿陷性黄土场地上的电力工程建设项目时,可以采用沉管挤密桩处理地基,处理深度可设定为12m,这一深度不仅能有效挤密桩间土,消除地基湿陷性,降低地基渗透系数,还能使处理深度范围内的土层形成良好的承载层和隔水层,从而保证地基的稳定性和工程的安全性。This article analyzes the immersion test results of compacted foundation on collapsible loess sites and explores the depth of foundation treatment with immersed tube compacted piles.It is recommended that when dealing with power engineering construction projects on thick and collapsible loess sites,sinking tube compaction piles can be used to treat the foundation,and the treatment depth can be set to 12 meters.This depth can not only effectively compact the soil between piles,eliminate foundation collapsibility,reduce foundation permeability,but also form a good bearing layer and waterproof layer in the soil layer within the treatment depth range,thereby ensuring the stability of the foundation and the safety ofthe project.
