摘要
利用在土工格栅上固定柔性位移传感器的方法,对土工格栅加筋路堤以及路基纵向填挖交界处路面裂缝处治试验路中的格栅应变进行了两年多的观测。观测结果表明,实际工程中土工格栅的变形主要来源于施工的影响;格栅正常工作中,应变均处于较低的水平,路堤填土带给格栅的变形随格栅上部填土厚度的增加而增大;路基完工6～8个月后,格栅的应变趋于平稳,达到最大值;
The two-year observation on the strain of geogrid in the trial road for dealing with the pavement cracks at the reinforced embankment and the longitudinal fill-cut interface of subgrade was carried out by using the flexible pavement sensors fixed on the geogrid. The observed results have shown that the deformation of the geogrid used in the works is influenced mainly by the construction. In normal cases, the strains of geogrid are at the lower level, and the deformation from the fill of embankment would increase with the depths of top fill on the geogrid, the strain of geogrid tends to the steady and reaches the maximum value after the completion of project in a period of 6-8 months. The infiltration of rainwater is unfavorable for the stability of reinforced embankment with geogrid.
