Abstract This study focuses on the three-dimensional effect and defect quantitative analysis method of large-diameter piles in low strain integrity test. A coupling vibration model of variable cross-section piles and surrounding layered soil was proposed. A frequency-domain analytical solution of the longitudinal vibration response at any position of the pile，considering the three-dimensional fluctuation of the pile body，was obtained by establishing a recurrence relationship between the layers，and a semi-analytical solution in time domain was deduced with inverse Fourier transform. Then the amplitude attenuation and travel time of the incident velocity wave along radial or longitudinal directions of the pile under different conditions were discussed. Finally，a field test was carried out to investigate the longitudinal vibration response at different positions of a concrete pile，and the rationality of the analytical solutions was verified. The results show that the three-dimensional effect of a large-diameter pile in low strain integrity test is significant and the influence depth is related to the action area and duration of the excitation force on the pile top. The longitudinal attenuation characteristics of the velocity wave can well reflect the integrity of the pile body and the surrounding soil resistance. The research work provides a new method for testing the integrity of piles and has certain engineering application value.

Key words： pile foundation large-diameter pile low strain integrity test three-dimensional effect amplitude attenuation field test
