【摘要】：文物保护中的安全监测是一项复杂而重要的工作,为了确保具有千年历史的独木舟从出土到馆藏过程中的结构安全,提出了采用分布式光纤传感的全过程应变监测方法。首先结合工程实际情况,确定整体分布式光纤监测方案,优化了光纤的布设方法。通过分布式应变监测数据评估了加固保护和翻转过程对舟体的影响。监测结果表明,分布式光纤传感能有效地捕捉各过程的结构应变变化,分析表明该文物保护过程中舟体处于安全状态。实际工程应用也验证了分布式光纤传感技术在文物结构安全保护过程中的有效性,该方法具有极大的推广价值,能有效提高现有文物挖掘保护水平。
[Abstract]:The safety monitoring in the protection of cultural relics is a complex and important task. In order to ensure the structural safety of canoe with a millennium history from unearthed to the collection, a new method of strain monitoring using distributed optical fiber sensing is put forward. Firstly, according to the actual situation of the project, the whole distributed optical fiber monitoring scheme is determined, and the layout method of the optical fiber is optimized. Based on the distributed strain monitoring data, the effects of reinforcement, protection and flip-over on the boat body were evaluated. The monitoring results show that the distributed optical fiber sensing can effectively capture the structural strain changes in each process, and the analysis shows that the boat body is in a safe state during the process of preservation of the cultural relic. The effectiveness of distributed optical fiber sensing technology in the process of security protection of cultural relics has also been verified in practical engineering. The method has great value of popularization and can effectively improve the existing level of excavation and protection of cultural relics.
