陡坡段高路堤变形监测与分析

Deformation monitoring and analysis of high embankment in steep slope section

为验证陡坡路段高填方路堤的稳定性,结合某施工实例,在施工过程中开展变形监测,并对监测结果进行了分析,结果表明:高填方各类路堤沉降变形随路堤填筑高度增加而增加,地表沉降完工后仍存在小幅度蠕变变形,深部水平位移和不均匀沉降主要发生在路堤中部。各类变形均超过预警值,基本可以排除产生大变形的可能性,但还需要进一步开展监测验证路堤的稳定性。

In order to verify the stability of high-fill embankments in steep slope sections, combined with an engineering example, deformation monitoring was carried out during the construction process, and monitoring results were analyzed. The settlement deformation of various embankments of high-filled roads increases with the increase of the embankment height. After the surface settlement is completed, there still exists a small amount of creep deformation, and the deep horizontal displacement and uneven settlement mainly occur in the middle of the embankment. All types of deformation exceed the warning value, and the possibility of large deformation can basically be ruled out. However, further monitoring is needed to verify the stability of the embankment.
