Asphalt pavement strain signal preprocessing method
The invention discloses an asphalt pavement strain signal preprocessing method, and belongs to the technical field of road engineering. The method comprises the following steps: arranging a strain acquisition sensor; acquiring a strain signal generated by a road test through a strain acquisition sensor; carrying out filtering processing on the strain signal; intercepting the effective part of the strain signal; and automatically identifying the peak and valley values of the strain signal. According to the method, the real state of the asphalt concrete pavement is simulated through pavement testing, load response strain signals are collected, a large amount of actual measurement data are provided for accurately determining the strain condition of an asphalt layer in a pavement structure, wavelet filtering processing is carried out on the original strain signals, the signal-to-noise ratio of the original signals can be increased, and the measurement accuracy is improved. Effective fragment synthesis is carried out on the filtered signal, the storage difficulty is reduced, the analysis efficiency is improved, peak-valley value marking is carried out on the synthesized signal, the marking accuracy is greatly improved, and a good foundation is laid for fatigue damage research and life prediction of the asphalt concrete pavement.
