This paper investigates the influence factors of impact force of bridge piers in collision with ship.Take the impact of circular pier with 500t ship for example,the simulation model of cylindrical pier was established by using LS-Dyna dynamic simulation software,and the sensitivity of ship impact parameters,including ship impact velocity,impact angle,diameter of the pier were analyzed.The sensitivity coefficient influence factors are discussed,The result shows that the impact force increases nonlinearly with the velocity increase and decreases nonlinearly with the angle increase,meanwhile,the influence of diameter on impact force is very little,which can be ignored for cylindrical pier.
