Selection of Pile Testing Signals for Parallel Seismic Test
It is difficult to apply the common nondestructive method to the pile with an inaccessible head condition. The Parallel Seismic test, however, is a promising method that can be used to deal with such difficulties. On the basis of the physical mechanism of P-wave and S-wave, comparisons of the characteristics of the volumetric and shear strain signals, as well as vertical and horizontal vibration signals have been made, providing the theoretical basis for adoption of P-wave and PS-wave as a combination.
