【摘要】：文物保護中的安全監(jiān)測是一項復雜而重要的工作,為了確保具有千年歷史的獨木舟從出土到館藏過程中的結構安全,提出了采用分布式光纖傳感的全過程應變監(jiān)測方法。首先結合工程實際情況,確定整體分布式光纖監(jiān)測方案,優(yōu)化了光纖的布設方法。通過分布式應變監(jiān)測數據評估了加固保護和翻轉過程對舟體的影響。監(jiān)測結果表明,分布式光纖傳感能有效地捕捉各過程的結構應變變化,分析表明該文物保護過程中舟體處于安全狀態(tài)。實際工程應用也驗證了分布式光纖傳感技術在文物結構安全保護過程中的有效性,該方法具有極大的推廣價值,能有效提高現有文物挖掘保護水平。
[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.
