| Abstract: | Based on the extensive use prospect of Acoustic Emission technology in concrete damage detection, researches on acoustic emission analysis methods of concrete damage at home and abroad were analyzed. The sorting of Acoustic Emission analysis methods for concrete damage was focused on four aspects: characteristic parameter analysis of Acoustic Emission signal of concrete damage, waveform analysis of Acoustic Emission signal, concrete damage location analysis based on Acoustic Emission technology, and application of Acoustic Emission technology for concrete structure damage under fire. The research status of various Acoustic Emission analysis methods was introduced, and their technical characteristics and application scope were summarized. |
