基于德国标准高速铁路桥涵框架结构设计

Design for High-speed Railway Bridge and Culvert Frame Structure Based on German Code

某国外沿海高速铁路主要采用德国联邦铁路DS标准及德国工业DIN标准进行施工图设计,其中桥涵结构以框架结构为主。本文结合国际咨询及施工图设计,论述基于德国标准的框架结构设计要点,主要从结构形式、结构计算、荷载分析、耐久性设计等方面阐述框架结构设计特点,以及与我国高速铁路在设计理论、建筑材料、结构构造等方面的主要差异,以期为类似国际工程提供一些设计方面的技术参考。

The overseas coastal high-speed railway studied in this paper complies with DS and DIN specifications for work-ing drawing design,where the bridges and culverts mainly adopt frame structures.In combination with the international consultation and working drawing design of this high-speed railway,this paper discusses the key points of the frame struc-ture design based on German code,which mainly covers the design features of frame structures in terms of structural type, structural calculation,load analysis,durability design,etc.,as well as the main design differences with Chinese high-speed railway in respect of the design theories,construction materials,structure construction,etc.,so as to provide techni-cal references for similar international projects.
