Foundation pile detection method and system and storage medium

The invention relates to the technical field of foundation pile detection, and discloses a foundation pile detection method and system and a storage medium. The method comprises the steps that varioustypes of defects of a foundation pile are modeled into a reduced cross-sectional area of the foundation pile in advance, and the mapping relationship between the damage degree and integrity coefficient of the foundation pile are matched and set; a low-strain reflected wave method is used to actually measure the vibration velocity time-domain graph of the pile top of the foundation pile, and a damage position of the foundation pile is obtained; based on the damage position, the low-strain reflected wave dynamic fingerprint with different damage degrees is calculated through an analytical solution to dynamic problems of the foundation pile, and an approximate function relationship is obtained; a foundation pile integrity coefficient eta is obtained through calculation; and a foundation piledamage level is obtained
