Method, device and system for processing signal of geotechnical engineering medium
2016
The invention provides a method for processing a signal of a geotechnical engineering medium. The method for processing the signal of the geotechnical engineering medium comprises the steps that surface normal direction speed or accelerated speed waveform data in elastic wave signals of all detecting points on the same detecting line is acquired, the waveform energy values of all the detecting points on the same detecting line are determined, and the defect depth value on the same detecting line is determined according to the waveform energy values. According to the method, device and system for processing the signal of the geotechnical engineering medium, the actual engineering detecting need is adopted as a background, the influence of defect depth on response waveform energy is defined, and the internal defect depth of the complex geotechnical engineering medium can be easily and precisely detected at low cost.
