基于光纤的固有物性属性,光纤传感器已成为智能结构的首选智能材料。2003年,光纤传感器首次应用于云南省的隧道监测——嵩待高速公路的白泥井3号隧道。在点式和分布式光纤传感器的联合监测系统中,光纤Bragg传感器在每断面上有5个粘贴点,而Brillouin OTDR按3条纵向和一条绕拱粘贴。
Based on inherent physical properties of optical fiber, optical fiber sensors have become the smart materials of choice for intelligent structures. In 2003, the optical fiber sensor was first applied to the tunnel monitoring in Yunnan Province - Songjing Expressway Bai Naijing No. 3 tunnel. In a combined monitoring system for point and distributed fiber optic sensors, the fiber Bragg sensor has 5 points of attachment per cross section, while the Brillouin OTDR is applied in 3 longitudinal and one winding ways.
