Analysis on Automatic Monitoring System of Valley Amplitude(sine curve)Deformation——Taking Lijiaxia Hydropower Station as an example

为分析谷幅(弦线)变形监测自动化系统的可靠性,利用李家峡水电站谷幅(弦线)自动化采集数据,使用最小二乘法分析日均谷幅(弦线)变形值,得出该谷幅(弦线)自动化采集数据的精度可满足1 mm+1 ppm的监测需求,该自动化系统可为拱坝谷幅(弦线)监测提供可靠的数据支持。

In order to analyze the reliability of the automatic monitoring system for valley amplitude(sine wave)deformation,the least square method is used to analyze the daily average valley amplitude(sine wave)deformation value collected by the automatic monitoring system of Lijiaxia Hydropower Station.The result shows that the accuracy of the collected data of valley amplitude(sine wave)meet the monitoring requirements of 1 mm+1 ppm,and the automatic system can provide reliable data support for the monitoring of the valley amplitude(sine wave)of the arch dam.
