Analysis on Dynamic Response Characteristic of Bridge Pier Based on the Influence of Underwater Drilling and Blasting
The influence of underwater drilling and blasting on the dynamic response of bridge pier is analyzed by numerical simulation.By establishing a detailed material model and state equation for bridge piers,water media,rocks and explosives,the velocity,acceleration and displacement responses during the blasting process are simulated in detail.The research shows that reasonable simulation analysis can significantly improve the accuracy of the safety assessment of underwater engineering,and provide scientific basis for the protection and maintenance of underwater structures such as bridges.The purpose of this paper is to improve the safety and reliability of bridges in extreme environments,and to provide technical reference and theoretical support for the anti-explosion design and safety assessment of related engineering.
