Stainless-steel reinforcement is used to replace the common reinforcement of RC pier in the marine environment, so as to solve the corrosion issue of reinforcement. According to the collision force of stainless-steel reinforced concrete bridge pier under cumulative impact, in this paper the cumulative impact loss factors of the pier is considered to analyze the relationship between the pier stiff ness and ultrasonic sound velocity by numerical simulation. The calculation formula of the collision force considering the cumulative impact damage of the pier is then created with the experimental verifi cation and comparative analysis of relevant norms. The results show that the formula of the collision force proposed in this paper is able to better refl ect the actual force of the cumulative impact of the pier.
