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 according to the integrity coefficient eta. According to the invention, the quantitative analysis problem of the damage degree of the foundation pile is effectively solved, and the accuracy and practicability of the low-strain reflected wave detection method for foundation pile damage identification are improved.
