| 摘 要： | 光照电站是北盘江上大型水利枢纽，为确保安全施工和运营，采用智能型全站仪TCA2003对大坝两岸边坡进行位移变形监测。由于监测结果中包含测量仪器、测量条件和测量过程误差，利用db3小波和db6小波进行去噪处理，获取更具真实性和稳定性的数据。通过对比分析，db6小波去噪效果比db3小波好，调用函数提取db6小波分解前后的高频系数，可以判断出噪声主要集中在高频中前两层。

| Abstract: | Irradiation Station was a large-scale hydro-junction of beipan river,in order to ensure security construction and operation,we adoptted Intelligence Total Station TCA2003 to monitor displacement deformation of the two sides slops of the dam.Because the monitoring results included measuring instruments,measuring conditions and measurement process errors,we took advantage of db3 wavelet and db6 wavelet to denoise observation data to obtain much more authenticity and stability data.Through contrasting and anal... |
