针对新建客用专线首次采用的铁路路基孔隙率检测标准进行了检测方法的研究试验,介绍了两种孔隙率测试方法,并分析了对比试验的结果,得出了通过测定填料颗粒毛体积密度和现场碾压干密度来检测孔隙率的方法适用于路基压实检测的结论。 According to the testing method of the test method for the permeability of railway subgrade used for the first time in newly-built passenger dedicated line, two methods for testing the porosity were introduced and the results of the comparative test were analyzed. It was obtained that by measuring the gross bulk density of the filler particles and The method of checking the porosity by dry compaction on site is suitable for the conclusion of subgrade compaction testing.
