Then a three-dimensional shear wave velocity model is constructed with the detection point as the core. By analyzing the wave velocity change in the vertical and horizontal directions, the abnormality of high-speed and low-speed areas, it is inferred whether there is a pile foundation under the area, and effective guidance is provided for the subsequent construction process selection.
