Testing and analyzing method for intelligent detection on integrity of foundation piles by using acoustic transmission method

2016 
The invention discloses a testing and analyzing method for intelligent detection on integrity of a foundation piles by using an acoustic transmission method. The testing and analyzing method comprises the following steps: by taking acoustic transmission method detection data files as basis, calculating sound velocity, head wave amplitude, waveform distortion coefficients, frequency distortion coefficients and signal energy, performing acoustic parameter abnormal critical value calculation and abnormal classification, classifying measuring lines according to the classification result, classifying horizontal sections according to the classification of the measuring lines, furthermore, confirming abnormal sections of a pile body to form horizontal section chromatograms, and overlapping the horizontal section chromatograms so as to form three-dimensional chromatograms, namely, pile body defect distribution diagrams. The testing and analyzing method is based on acoustic detection technical principles and engineering detection practical experience, quantitative analysis on sound parameter calculation, judgment, classification, comprehensive analysis, graphic display and the like can be implemented, the workload and the difficulty of artificial analysis in the data analysis process can be reduced, the mal-judgment risk can be reduced, the information content of the detection result is enriched, the abnormal degree and the spatial distribution of the pile body defects can be visibly displayed in the pile body defect distribution diagrams, and the accuracy and the reliability of the detection result are improved.
