摘要
叙述了用瞬态冲击频谱分析法测定路基压实度的原理和技术关键。运用Ｓ—Ｇ水滞频段，无需测量土的含水量，就能快速、无损、定量的测定土的压实度。
In this paper, a method of shock frequency analysis is applied to compaction measurement. Its principle and key technique is given. Because of the S-G water frequency band being used, it is possible to fast and nondestructive measure compaction of subgrade without water content measuring.
