Study On Funabashi Collisions And Anti-Collision Bridge Pier Facilities

With continuous development of transportation,traffic of ship,automobile and train,increased heavily.Funabashi collisions caused more and more Bridge collapse. Statistics show that the most recent decades,the world's ship collision happened bridge pier destroyed a major accident on more than more than 100.Such incidents are often caused by a bridge structure,the life,safety and anti-seismic capacity loss may result in a serious crash and death of people such as the bridge to disastrous consequences. Therefore,to carry out collision and bridges funabashi research facilities,improve the crashworthiness bridges are of great significance.In this paper,the collision funabashi pier facilities and research at home and abroad have been elaborated;on the water around the pier structure analysis laid the bridge opening,taking into account the construction of a bridge pier on the river bed after the impact of evolution,not to the downstream river flow and channel conditions have a significant impact on the conclusions;the impact of the bridge of the ship and bridge collision mechanism of research,described the collision funabashi research methods commonly used in research that the computer simulation technology in the ship hit the bridge study has become an increasingly widespread application;through access to literature at home and abroad,according to Japanese scholars Satoshi Iwai·pier facilities proposed by the classification method,the crash of the pier facilities on a comprehensive and commonly used in several of China's anti-collision protection system comparison,the steel box-type anti-collision devices better;in accordance with Satoshi Iwai·pier facilities proposed by the classification method,the current bridge has been the use of facilities,as well as a review of the application of occasions;in Bridge-to-ship collision analysis of research methods on the basis of the combination of the existing bridge collision facilities,use of ship collision facilities conclusion nonlinear finite element method proposed funabashi collision protection and improvement of the structural optimization program,namely:increase the horizontal strengthening ribs can be used as the structure of the bow to improve the crashworthiness of a way;the energy absorption of thin-walled tube characteristics than other types of aggregate better wall plate can be significantly improved energy absorption effects,can be anti-collision device Application of the design to improve its crashworthiness,and to improve their crashworthiness performance;stiffened panel grid layout of the form of energy absorption characteristics of the external panels have a significant impact,a reasonable buy cloth reinforcement material can save the structure can effectively improve the energy absorption rate.Finally,this paper summarized the research work and research prospects.This paper aims at summarizing the principles of the anti-collision about bridge pier and anti-collision facilities,hope to have some reference value for the job of bridge pier protection.
