Selection of Pile Testing Signals for Parallel Seismic Test
Jing Yi Zhang, Long Zhu Chen · Advanced materials research · 2011
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.
