【摘要】：文物保護(hù)中的安全監(jiān)測(cè)是一項(xiàng)復(fù)雜而重要的工作,為了確保具有千年歷史的獨(dú)木舟從出土到館藏過(guò)程中的結(jié)構(gòu)安全,提出了采用分布式光纖傳感的全過(guò)程應(yīng)變監(jiān)測(cè)方法。首先結(jié)合工程實(shí)際情況,確定整體分布式光纖監(jiān)測(cè)方案,優(yōu)化了光纖的布設(shè)方法。通過(guò)分布式應(yīng)變監(jiān)測(cè)數(shù)據(jù)評(píng)估了加固保護(hù)和翻轉(zhuǎn)過(guò)程對(duì)舟體的影響。監(jiān)測(cè)結(jié)果表明,分布式光纖傳感能有效地捕捉各過(guò)程的結(jié)構(gòu)應(yīng)變變化,分析表明該文物保護(hù)過(guò)程中舟體處于安全狀態(tài)。實(shí)際工程應(yīng)用也驗(yàn)證了分布式光纖傳感技術(shù)在文物結(jié)構(gòu)安全保護(hù)過(guò)程中的有效性,該方法具有極大的推廣價(jià)值,能有效提高現(xiàn)有文物挖掘保護(hù)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.
