| Abstract: | The major difference between the high-piled wharf pile and the single pile is the existence of superstructures. The superstructures exert apparent 3D effect on the strain wave propagation in the high-piled wharf piles. Based on the research of pile integrity detection at home and aboard, the propagating characters and deference between the ordinary single pile and the high-piled wharf pile are systematically introduced. The problems including the best location of knock and signal reception which calls for immediate solution of the highpiled wharf pile integrity detection are also introduced. Also the research ideas including the application of the FEM numerical simulation and wavelet analysis are introduced. |
