摘　　要：为确定采用特殊土填筑路堤的稳定性,布置测点开展监测进行数据分析。采用埋入式沉降板法对路堤沉降进行监测,得出路堤沉降量和沉降速度在施工期较大,预压期较小,且已基本达到稳定状态。路堤侧向水平位移变形量与变形速率变化趋势与路堤沉降类似,且监测结束后达到了稳定状态,说明该段路堤施工质量合格。In order to determine the stability of embankment filled with special soil,measuring points were arranged to carry out monitoring and data analysis.The embankment settlement is monitored by the embedded settling plate method,and it is concluded that the embankment settlement and settlement speed are relatively large during the construction period,and the preload period is relatively small,and it has basically reached a stable state.The change trend of the lateral horizontal displacement and deformation rate of the embankment is similar to the settlement of the embankment,and it has reached a stable state after monitoring,indicating that the construction quality of this section of embankment is qualified.
