摘要
SDG密度仪是一种基于电磁学原理的密度检测仪,在用于路基填土压实度检测过程中,可进行现场压实填土密实度的快速无损检测,从而实现对现场填土压实质量的动态实时检验与控制。根据密度仪的特性实施现场与室内模拟试验,结果显示SDG密度仪具有良好的稳定性与可靠性,适合于黏性填土密度的快速无损检测,尤其是对于干密度为1.5 g/cm3以上的黏性填土显示良好的准确性与可靠性。
SDG is a density gauge based on electromagnetism principle.It could be used as a rapid nondestructive detecting method to detect subgrade compaction,which is helpful to real-time dynamic detecting of subgrade compaction.With site and laboratory tests,it cloud be concluded that the SDG is suitable for compaction detecting of clayey embankment with favorable stability and dependability,especially for the clayey embankment which dry density is near or above 1.5g/cm3.
