摘要
结合南邓高速公路的路基施工,系统阐述了石灰土作为一种路基填筑材料,在处理膨胀土路基时的强度形成机理和施工技术,并着力说明在此过程中关键工序的操作工艺,对膨胀土地区的高速公路建设具有一定的借鉴意义。
According to the subgrade construction in Nandeng expressway, this paper systematically elaborates the strength formation mechanism and construction techniques of lime stone as a kind of subgrade embankment material in processing expansive soil subgrade. It also illustrates the operation techniques of key working procedures, providing some guidance for the expressway construction in the expansive soil region.
