Study on the Influence of Pile-soil Interaction Simulation Method on Dynamic Response Characteristics of Anti-collision Piles
The finite element model of collision between a 2000t class ship and a single pile was estab-lished.By extracting the displacement time-history curve and impact force time-history curve of the pile top,this paper discussed the influence of two different pile-soil interaction simulation methods,namely,the fixed end constraint model and the pile-soil surface contact model,on the collision result between the ship and the anti-collision pile.The results show that the collision process between the ship and the anti-collision pile has gone through four stages.When the pile-soil interaction adopts the fixed-end constraint model,the response characteristics are greatly influenced by the pile length,which can be used to simulate the ship-bridge collision equivalently under certain conditions.The con-tact model between pile and soil can reflect the interaction between pile and soil more truly,and the buried depth of pile and the initial speed of ship have great influence on the dynamic response of pile.
