| 摘 要： | 针对目前桥墩被船撞事故的频发,研究了某大桥水中桥墩在船撞作用下的响应,分别按照公路桥涵04规范、铁路规范、欧洲规范的要求采用不同的船舶撞击力,对各撞击力作用下桥梁墩柱结构进行计算、分析、比较。在3种规范对船舶撞击力的规定中,公路规范取值最小,铁路规范次之,欧洲规范最大,由此在桥墩防撞设计时应引起设计人员足够的重视。

| Abstract: | In connection with the frequency of ship-pier collision accidents,this paper discusses the response that ships hit the bridge piers in the river.According to the provision of the general code of highway bridges,the fundamental code on railway bridge and Eurocode 1,different impact force is adopted,which supplies reliable foundation for the design of anti-collision of bridge pier by means of calculation and analysis on pier structure.Among the three codes,the value of the highway bridge code is the least,the... |
