欧洲统一规范Eurocode1-船撞桥梁偶然作用评述

摘要

总结了欧洲统一规范Eurocode 1在冲击和爆炸偶然作用设计方面的总体思想和关键条文,对其关键条文如船撞力、船只撞桥概率和桥梁倒塌概率作了详细解释和推理后,指出其在上述方面存在的不足之处,并提供了相应的修改建议,以供国内桥梁船撞设计、研究对比和参考.%General thoughts and key items of Eurocode 1- Accidental actions on structures due to impact and explosions were summarized, thorough interpretation and reasoning was given to ites key items such as vessel collision force, probability of vessel collision bridge and probability of bridge collapse. Shortcomings of above areas was pointed out as well as some modification suggestions was given. All those offer a good comparison and reference to our country 's bridge design, research against vessel collision.
