水库大坝质量的好坏对于保证库区居民用水以及汛期防洪有着极为重要的作用。因此,坝堤质量的检测及加固工作显得十分重要。瑞雷波法是一种快速、无损、经济的检测方法。通过瑞雷波测试坝堤内部介质波速的大小分布,利用波速大小与介质密实度相关的关系,从而快速推断坝堤内部相对薄弱的区域,为下一步的坝堤质量评价及加固方案提供依据。
The quality of the reservoir dam is very important for ensuring the residents’ water in the reservoir area and flood control in flood season. Therefore, dam dike quality testing and reinforcement work is very important. Rayleigh wave method is a fast, non-destructive, economical method of detection. By Rayleigh wave testing the distribution of medium wave velocity inside the dam and using the relationship between wave velocity and medium density, the relative weak area inside the dam can be quickly inferred, which provides the basis for the next dam embankment quality evaluation and reinforcement.
