摘要
基于分布式光纤测温技术的优势,针对其在大坝混凝土施工期测温过程中的要点,阐述了相应的布线、定位、铺设、保护、连接等工艺,并对光纤在线测温技术提出了改进建议。以金沙江溪洛渡水电站和大渡河深溪沟水电站成功应用实例证明,该法行之有效,准确可靠,为有效评估大坝安全提供了可靠依据。
Based on the advantages of distributed optical fiber temperature measurement technique and the key points of temperature measurement during the dam concrete construction, the corresponding techniques of routing, positioning, laying, protection, connection are represented. And improved suggestions of optical fiber real time temperature measurement technique are proposed. Take the process of temperature measurement in Xiluodu Hydropower Station on the Jinsha River and Sbenxigou Hydropower Station on the Dadu River for an example. The results show that the proposed method is effective, reliable and accurate. Thus, it provides basis for the dam safety assessment.
