摘　　要：本文阐述高砼面板堆石坝面板挠度监测技术的最新进展,作者提出并首次在思安江砼面板堆石坝实现砼面板挠度三维光纤陀螺(FOG)系统的测量技术,取得令人关注的科研成果。研制的三维光纤陀螺具有小动态、高精度的特点;FOG系统运行管道和测量小车的设计是合理的,且测值稳定、可靠、重复性好。New development of the slab deflection measurement for high concrete faced rock-fill dam is presented in this paper. The technology of three dimensional Fiber Optic Gyro（FOG） system is proposed and applied to measure the slab deflection of the Si-anjiang concrete faced rock-fill dam, and remarkable results are achieved. The FOG is developed in small dynamic state and in high accuracy; its operating pipe and the measuring vehicle are reasonable in design, and the testing values are steady, reliable, and good at repeatability.
