摘要
分别阐述了我国公路和铁路规范中桥梁船舶撞击力的确定方法和相应的桥梁下部结构的力学计算模型,介绍了AASHTO规范中对于船舶撞击桥梁的风险评估方法的方法,并给出工程计算实例,提出了针对我国具体情况开展适合我国国情的船舶撞击桥梁风险评估的建议。
The methods of determining the vessel impact force according to China railway code and China highway code are introduced respectively. Risk assessment procedures of vessel impacts on bridge published by AASHTO and an example are introduced. The suggestion of developing Chinese risk assessment method for vessel impacts on bridge is put forward.
