摘　　要：由于软土地基具有含水量高、压缩性大等特点,导致高速公路软基路堤沉降严重。文章研究了高速公路软基路堤沉降防治措施,以某实际工程为例,用钻机钻取注浆孔,以超细水泥为原材料配制浆液,确定注浆量、注浆压力、注浆速度等施工参数后进行注浆,完成了高速公路软基路堤沉降防治施工。结果表明,工后软基路堤最大沉降量为19.06 cm,在允许范围内,证明了设计防治措施的有效性。Due to the characteristics of high water content and high compressibility of soft soil foundation,the soft foundation embankment settlement on expressways is serious.This paper studies the prevention and control measures for soft foundation embankment settlement on expressways.Taking a practical project as an example,the grouting hole is drilled by drilling machine,and the slurry is prepared with ultrafine cement as raw materials.After determining construction parameters such as grouting amount,grouting pressure and grouting speed,the grouting is carried out,and the soft foundation embankment settlement prevention and control construction on expressways is completed.The results show that the maximum settlement of the soft foundation embankment after construction is 19.06 cm,which is within the allowable range,proving the effectiveness of the designed prevention measures.
