Abstract
Ice structures provide load-bearing capability for energy exploitation and transportation in cold regions. Meanwhile, staff and facilities take a risk due to large amounts of distributed macrocracks in ice roads, ice bridges, and ice platforms. It is critical to monitor macrocracks for detecting and understanding the fracture process under such a harsh environment. Aiming to obtain real-time, long-term, and quantitative crack opening information for ice structures, this paper presents a feasibility study on monitoring macrocracks with a low modulus polymer packaged optical fiber sensor. Brillouin optical time-domain analysis-based sensing technology is utilized for the distributed strain measurement. According to
