本文主要阐述路基地质情况属于湿陷性黄土的处理方法,湿陷性黄土是一种大孔隙率和垂直节理发达的黄色粉土。这种土没有水的时候强度高,稳定性好,但是一旦遇到水后,土中的的部分介质极易溶于水,其强度会迅速下降,对路基建设造成很大的危害。根据施工经验和科学研究,湿陷性黄土通常是采用灰土挤密桩、水泥搅拌桩和换填法等方法进行加固处理。
This paper mainly discusses the subgrade geological conditions belong to collapsible loess processing method, collapsible loess is a macroporosity and vertical joint developed yellow silt. When the soil does not have water, it has high strength and good stability. However, once it encounters water, part of the medium in the soil is easily dissolved in water and its strength will drop rapidly, which will cause great harm to the subgrade construction. According to construction experience and scientific research, collapsible loess is usually reinforced with lime-soil compaction piles, cement mixing piles and replacement methods.
