摘　　要：阐述了高混凝土面板堆石坝面板挠度监测技术的最新进展,提出并首次在思安江混凝土面板堆石坝实现了混凝土面板挠度光纤陀螺(FOG)系统的测量技术,取得了令人关注的科研成果.研制的光纤陀螺具有小动态、高精度的特点;FOG系统运行管道的设计是合理的,且测值稳定、可靠、重复性好.New development of slab deflection measurement for high Concrete Faced Rockfill Dam(CFRD) is introduced. Fiber Optic Gyro (FOG) system is proposed and first applied to measure slab deflection of the CFRD of Si Anjiang river, and remarkable results have been achieved. The developed FOG is stable in dynamic state and high in accuracy, and its operating pipe is reasonable in design, and the measurement values are steady, reliable, and good in repeatability.
