摘　　要：分布式光纤声波传感(DAS)技术以独特的动态在线监测、大范围密集测量、方便布设免维护等优势,获得了周界安防、结构健康、交通运输、油气勘探、海洋水声等多领域专家学者的广泛关注。同时,DAS技术可以方便地通过标准通信光缆或专用光缆形成大规模探测阵列,满足地球物理与自然灾害预测等领域的地震波检测需求,有望得到更广泛的应用。以新兴的地震波检测应用为切入点,结合调研情况,对DAS技术的基本传感原理、技术发展历程、地震波应用进展等进行论述,并分析DAS在地震波检测方向所面临的关键技术难题和未来发展趋势。Distributed optical fiber acoustic sensing(DAS) technology provides unique advantages such as dynamic online monitoring, long-haul dense measurement, convenient installation, and maintenance-free operation. Hence, it has attracted extensive research attention in various fields, including perimeter security, structural health monitoring,transportation, oil and gas exploration, and submarine acoustics. Combined with standard communication optical cables or dedicated optical cables, DAS can conveniently form large-scale detection arrays, meet the requirements of seismic wave monitoring for geophysics and natural disaster detection, and achieve applicability in diverse fields. This paper is focused on the emerging seismic wave monitoring application of DAS. In particular, the basic sensing principles, technology development, and application progress of DAS-based seismic wave monitoring are discussed. In addition, the key technical problems and future development trends of DAS for seismic wave detection are analyzed.
