AI Technical Summary

Technical Problem

Existing intelligent diagnostic models and integrated systems for pile foundation integrity rely on manual interpretation, which is highly subjective, results are not repeatable, and lacks quantitative calculation support. This leads to low accuracy in defect location and severity assessment, failing to meet the engineering requirements for precise defect location and classification.

Method used

An intelligent diagnostic model based on ultrasonic transmission method is adopted. Through data acquisition, signal preprocessing, parameter feature calculation, intelligent judgment and integrity judgment modules, combined with DTW algorithm and Butterworth low-pass filter, a multi-level mathematical model and judgment logic for pile foundation are realized, and quantitative expert interpretation is achieved, thereby improving the accuracy and precision of defect identification.

Benefits of technology

It enables efficient and accurate identification and classification of pile foundation defects, eliminates the subjectivity of manual interpretation, improves the objectivity and consistency of test results, and adapts to the testing needs under different geological conditions.
