高液限土具有高天然含水率、高孔隙比和结构性强的特点,压实度普遍较低。为了明确高液限红粘土路堤的沉降变形规律,本文结合某高速公路建设,现场埋设传感器,对路堤沉降及其随时间变化规律进行了实测。结果表明:高液限红粘土路堤断面沉降分布呈现中间大、侧小的正态分布形状;高液限红粘土路堤填筑完成后,应经历8个月到一年的时间方可进行路面施工。 High liquid limit soil has the characteristics of high natural water content, high void ratio and strong structure, and generally low compaction degree. In order to clarify the law of settlement and deformation of embankment with high liquid limit red clay, this paper combines a highway construction, the site buried sensors, the embankment settlement and its variation with time were measured. The results show that the sediment distribution of the high liquid limit red clay embankment section shows a normal distribution with large middle and small side. After the filling of the high liquid red clay embankment is completed, it should be carried out for 8 months to one year before pavement construction .
