摘　　要：目前有多种传统的软土路基处理方法,但每一种处理方法都有明显的缺陷。为克服传统软土路基处理方法的缺点,在G341二十里沟口至车路崾岘一级公路软土路基处理中,采用了就地固化技术,提出了一种在软土中掺加“20%水泥+12.7%固化剂A”的方法,采用该固化剂进行就地固化处理后,该项目软土路基的承载力得到大幅提升。路基施工完成后,软土路基平均沉降值为19.7 cm,和天然地基段路基沉降值无明显差异。该施工方法与传统的换填法相比,可节省约34.8%的施工成本。There are many traditional methods for treating soft soil roadbeds,but each method has obvious defects.In order to overcome the shortcomings of traditional soft soil roadbeds treatment methods,the in-situ solidification technology was adopted in the treatment of soft soil roadbeds of G341 Ershiligoukou to Cheluyaoxian first-class highway with an agent of 20%cement and 12.7%curing agent A was proposed.After the in-situ solidification treatment with this curing agent,the bearing capacity of the soft soil roadbeds of the project was greatly improved.After the completion of the roadbed construction,the average settlement value of the soft soil roadbed is 19.7cm,which is not significantly different from the settlement value of the natural foundation section roadbed;Compared with traditional replacement methods,it can save about 34.8%of construction costs.
