摘要
本文介绍德国在高速铁路上建成的桥梁，其主要特点着重桥梁的刚度要大，易于检查维修，并采用国际联盟荷载ＵＩＣ７１。按照桥梁类别，阐述了预应力混凝土桥、钢梁、结合梁等设计内容，共同点在于把挠度限制在一定数值之内，并提供了不同桥型的断面图，可供我国设计高速铁路桥梁参考。作者认为ＵＩＣ荷载比较合理，再次建议我国改用ＵＩＣ７１荷载代替现行的中－活载。
The paper introduces the bridges built on the high speed railways in Germany.The main specialities of these bridges are high rigidity,easy to be inspected and repaired,as well as the application of UIC 71 standard loading.According to types of the bridge,the paper expounds the contents of the design for bridges with prestressed concrete girders,steel girders and composite beams.The common essential among these bridges is to limit their deflections within certain value.Besides,the different cross section of these bridges are proposed.They are valuable as reference for the design of the bridges on high speed railway in China.The author considers that the UIC standard loading is more reasonable,and suggests once more that we should apply the UIC 71 standard loading instead of the existing China railway standard live loading.
