摘　　要：水布垭水电站混凝土面板堆石坝采用光纤陀螺(FOG)监测面板挠度变形。通过对监测资料分析,全面揭示了水布垭面板堆石坝面板挠度变形特点和一般规律,即:面板挠度变形整体趋于收敛,坝高1/3附近和运行低水位高程附近面板反弹出现峰值。监测成果为大坝安全运行提供重要依据。Fiber-optic gyroscope is adopted for monitoring of the deflection deformation of the face-slab of the concrete face rock-fill dam for Shuibuya Hydropower Station. Through the analysis made on the monitoring data, the characteristics and the general law of the deflection deformation of the face-slab of the dam are fully revealed, i. e. the overall deflection deformation tends to convergence, while the rebounding of the face-slab with peak value occurs at both the location of 1/3 of the dam height and the elevation of the low operation water level. The monitoring achievement provides an important basis for the safety operation of the dam.
