摘要
针对秦沈客运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 ,详细介绍了 2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。
Based on the first application of standard for railway subgrade porosity test to Qinhuangdao\|Shenyang Passenger Special Line, the paper gives a detailed introduction to two testing methods, and analyzes comparative test results. It is concluded that the combination of bulk grain density and compacted dry density is the suitable method for testing the porosity of railway subgrade.
