| 摘 要： | 瑞利波波速与介质力学性质有良好的相关性,采用不同激振方法,在不同的含水量、压实度下利用DASP系统进行填石料中瑞利波频谱与波速分析,并将灌水法得到的密实度与瑞利波速度进行作非线性回归分析,建立填石料密实度与瑞利波速度的经验函数关系式,得到一种快速、无损、定量的填石路堤压实度检测方法。

| Abstract: | The rayleigh wave speed have good relativity with the medium quality mechanics,this article using different exciting ways, wave test was carried out under different water content and compaction degree, taking advantages of DASP system, frequency spectrum and wave velocity was analysed. In comparison with the measured compaction degree by watering method, an experience relational expression is set up between the compaction degree of rockfill and the velocity of Rayleigh wave, it is possible to fast,nondestructive and quantitative to measure compaction of Rockfill embankment. |

| Keywords: | Rockfill compatctness Rayleigh wave speed correlativity compaction detect |
