摘要
提出了一种大坝变形监测仪的系统结构及工作原理,重点介绍其光纤传感器的构造。该仪器在葛洲坝工程廊道试验运行了一年,其测量分辨率达5×10-3~6×10-3mm。该仪器结构简单,具有抗湿、抗电磁感应性能。
The architectural scheme of a sensing instrument for monitoring dam deformation is proposed;the structural design of the optical fiber sensor in this system is described emphatically.One-year testing operation in gallery of Gezhouba dam shows that this instrument has the behaviours of moisture-proof and anti-electromagnetic induction;its sensitivity reaches 5×10-3 mm-6×10-3 mm.
