摘　　要：软土地基会降低高速公路路基的承载能力,引起不均匀沉降,必须采取有效措施进行处治,并进行沉降观测。文章基于高速公路软土地基处理施工实践,阐述了软土地基的工程特点和处治方法,研究了软土地基沉降观测与数据处理内容,说明了采用抛石挤淤和土工格栅相结合的处治方式可有效提高软土地基的承载能力,控制路基不均匀沉降。Soft-soil foundation will reduce the carrying capacity of expressway subgrade and cause the uneven settlement,thus the effective treatment measures must be taken together with settlement observation.Based on the construction practice of expressway soft-soil foundation treatment,this article describes the engineering characteristics and treatment methods of soft-soil foundation,studies the settlement observation and data processing content of soft-soil foundation,and illustrates that the treatment method combining the riprap compaction and the geogrid can effectively improve the bearing capacity of soft-soil foundation and control the uneven settlement of the roadbed.
