张唐铁路(64+64)m T型刚构设计分析

Analysis on Design of 64m+64m T-type Rigid Framework for Zhangjiakou^Tangshan Railway

该文以新建张家口至唐山铁路工程T型刚构为工程背景,介绍(64+64)m T型刚构的结构特点及设计思路,并着重对T型刚构的桥型优势,梁体钢束布置,转体施工球铰局部效应,曲线T型刚构转动中心计算等进行了详细分析。所得结论可为同类工程的设计提供参考。

Based on the T-type rigid framework for the newly built Zhangjiakou- Tangshan Railway Project,this paper introduces the structural characteristics and design idea of the 64 m+64 m T-type rigid framework,and focuses analysis on the bridge advantages of T-type rigid framework, the layout of steel beam tendon, the local effect of spherical hinge by swing construction, the turning center calculation of curved T-type rigid framework in detail. Theconclusion can bereferred for thedesign ofthesimilar projects.
