Abstract: The influence of the surrounding vibration environment of cultural heritage on the cultural relics has become increasingly prominent, such as blasting, strong impact construction and so on. It is necessary to monitor the vibration environment and fix the position of the source of destructive impact on cultural relics, which can provide scientific basis and technical support for the heritage conservation?work. Based on the micro-vibration monitoring of Mogao Grottoes in Dunhuang, a source locating technique is proposed for dynamic compaction, blasting and other illegal industrial sources. Computer simulation results verify the effectiveness of the proposed method. ?The influence of formation and number of sensors on positioning are researched, and it is proposed that the formation and the number of sensors should be determined according to the vibration environment surrounding the cultural heritage, which provides a theoretical reference for the further development of the field test.
