Abstract：High-frequency monitoring data of cable-tower anchorage zone for Sutong Bridge shows that in the various noises leading to data distortion, topping structures such as cable tower is obviously affected by temperature and backward-sunflower phenomena is brought. In order to find out deformation of cable-tower caused by temperature and accurately evaluate the safety of cable-tower, combining real time meteorological date and construction schedule and adopting wavelet multi-scale denoising method by time scale, departure extent of cable tower brought by temperature is separated step by step. And deformation features of cable-tower anchorage zone brought by construction condition are extracted. Reliable calculation and analysis basis for the mechanic behavior of the anchorage zone and construction control. It has a good future in the field of engineering application for topping structure.
