摘要
以河南省襄城茨沟 -舞阳的二级公路改建工程为背景 ,通过分析落锤式弯沉仪测试结果 ,对土工格栅在提高路面承载能力所起到的作用进行了较全面的评价 ,并得到土工格栅在提高路面承载能力方面起到明显的改善作用这一结论。
Based on a reconstructed work case, i.e., XiangchengcigouWuyang Class Ⅱ Highway in Henan Province, with analysis on the test results from falling weight deflectometer, this paper gives a relatively allround evaluation on the role of geogrid in improving the bearing capacity of pavement and reaches a useful conclusion that the geogrid has an obvious role of improving the bearing capacity of pavement. Besides, it gives the methods of operating the falling weight deflectometer to test the bearing capacity of the widened part of old pavement and the cracked conditions of pavement.;
