Nondestructive testing with Rayleigh waves has been widely applied to engineering infrastructures and archaeological objects. Depending on the size of the objects under test and the spacial precision requirement, Rayleigh waves with different frequencies can be used. The key is to identify the stable and reliable dispersion features of the entire frequency band, especially those of high frequencies. The approach taken is the precise analysis of phase differences between waves of different frequencies on two measuring points. In this paper, we report two case studies associated with urban infrastructures. One is the test for the grouting treatment effect of a road foundation which has been disturbed by culvert propulsion across a highway. The other is the investigation of the weathering degree of a marble fence plate in the Forbidden City, Beijing. These two case studies offer our insight into the application of Rayleigh waves for investigating engineering objects in accordance to different sizes, the precision requirement, and other engineering interests.
