摘　　要：结合工程实例,通过对土工格栅在拓宽路堤中仪器的监测结果,测定了土工格栅应变与路基沉降差的正比增长关系,表明了格栅在路基垂直向位移过程中承受了剪拉力,可以增加新旧路堤的稳定性和整体性,更好地减少拓宽路堤的不均匀沉降。Combined with the engineering examples of widening embankment, through analysis of monitoring result of Geogrids, this paper measures the proportional increase relationship between Geogrids strain and differential subgrade settlement and indicates that grilles hold shearing strength during vertical displacement of foundation and can improve stability and integrity of new and old embankments and better reduce uneven settlement in widening embankment.
