In order to slow down the corrosion rate of concrete-filled steel tube structure of coastal highway bridge, it is necessary to quantitatively control the corrosion rate of concrete-filled steel tube structure of coastal highway bridge. A corrosion rate control method of concrete-filled steel tube structure of coastal highway bridge based on elastic modulus characteristic decomposition and adaptive evaluation of load stress is proposed. The constraint parameter model of corrosion speed control of concrete-filled steel tube structure of coastal highway bridge is constructed, and the corrosion damage degree response of concrete-filled steel tubular structure is evaluated with the method of force parameter estimation, and the corrosion rate of concrete-filled steel tube structure of coastal highway bridge is controlled. The quantitative regression analysis and adaptive control of corrosion rate of concrete-filled steel tube structure of coastal highway bridge are carried out by using yield stress response control method. The corrosion speed and tensile capacity of concrete-filled steel tubular structure of coastal highway bridge are tested, and the optimal estimation of corrosion rate parameters of concrete-filled steel tube structure of coastal highway bridge is realized. The simulation results show that the accuracy of using this method to control the corrosion rate of concrete-filled steel tubular structures of coastal highway bridges is high, and the corrosion resistance of concrete-filled steel tubular structures of coastal highway bridges is improved.
