“…In non-destructive testing, there is a crucial requirement for regulatory control, prompting the development of formalized algorithms to analyze measurement results. To quantitatively characterize the calculated spectrum, we introduce a set of spectral attributes that have been previously proposed for the analysis of seismic microzonation data, ground-penetrating radar, slab impulse-response tests [25][26], low strain impact, and parallel seismic methods for pile integrity testing [27][28]. These attributes include spectrum area Sn, normalized spectrum area Sn_norm, weighted mean frequency fw, and maximum frequency fmax.…”

“…Therefore, it is necessary to evaluate the integrity and quality of pile foundations and thus ensure the safety of supported superstructures. To detect the integrity of reinforced concrete (RC) piles, a variety of non-destructive testing techniques have been proposed successively, such as the low-strain pile integrity test (PIT) [ 1 , 2 , 3 , 4 ], sonic cross-hole logging (SCL) [ 5 , 6 , 7 , 8 ] and the parallel seismic (PS) method [ 9 , 10 , 11 , 12 , 13 , 14 ]. The existence of potential pile defects and unknown pile lengths can be detected by one method or a combination of multiple methods.…”
