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.

Key words: computer simulation, cultural heritage, source localization, sensor array, construction vibration, seismic wave

摘要: 文化遗产地周边振动环境对文物的影响问题日益突出,如爆破、强冲击施工等产生的环境振动对文化遗产地的文物安全可能会产生严重的影响,有必要对振动环境进行监测,同时定位对文物有破坏性影响的振源位置,为文物预防性保护工作提供科学依据和技术支持。研究了基于地振动的振源定位算法,提出适用于文化遗产地周边强夯、爆破施工等违规工业振源的定位方法,计算机仿真结果验证了该方法的有效性。研究了振动测点布设阵型和数量对定位效果的影响,提出了确定振动测点布设阵型和数量的方法,为进一步建设文化遗产地监测系统提供理论依据。
