Design of Concrete Quality Detection Software Based on Seismic Wave Field Time-Frequency Characteristics
摘要
The presence of voids in concrete can affect the safe service life of structures. Utilizing non-destructive testing methods such as acoustic, thermal, and electrical techniques for the quality inspection of concrete allows for the timely implementation of measures to address defects such as concrete voids. Among these methods, the elastic wave method is unaffected by the conductive properties of the medium and has strong applicability in the field. To facilitate rapid inspection and comprehensive quality assessment of large-volume concrete structures, this paper presents a software design that utilizes elastic wave data collected from one transmitter and two receivers. The software performs an integrated seismic wavefield analysis through time-domain, frequency-domain, and Rayleigh wave velocity spectrum, enabling accurate identification of voided areas in concrete. This enhances the efficiency of concrete quality inspections.
