【摘要】：结合光纤陀螺和加速度计测量堆石坝面板挠度的特点,利用卡尔曼滤波融合进行捷联解算,解决了光纤陀螺因长时间测量存在漂移影响测量精度、小车运行时有线性加速度加速度计无法准确测量动态倾角的问题。现场试验表明,多次试验结果的重复性较好,测量系统性能稳定,测点连续,精度较高,验证了该方法的可行性和有效性。为高混凝土面板堆石坝面板挠度变形监测提供了新的思路。
[Abstract]:Combined with the characteristics of fiber-optic gyroscope and accelerometer to measure the deflection of rockfill dam panel, the strapdown solution of fiber-optic gyroscope is solved by using Kalman filter fusion. There is the problem that the linear accelerometer can not accurately measure the dynamic inclination angle when the car is running. The field test shows that the repeated test results are good, the measurement system is stable, the measuring points are continuous, and the accuracy is high. The feasibility and effectiveness of the method are verified. It provides a new idea for deformation monitoring of face slab of high concrete face rockfill dam.
