东陵大桥改扩建设计

The Extension Construction Design of Dong Ling Bridge

随着交通运输的发展,早期修建的高速公路运行能力日趋饱和,高速公路的改扩建工程将是未来交通建设的一个重点。以东陵大桥改扩建为实例,简要介绍了大桥改扩建的设计原则、设计方案、影响T梁拼接的因素及处理措施、T梁的改造等方面的情况。

As the development of transportation, the operation capability of highways built in the early period has become increasingly saturated, so the extension construction of highways is a vital part in the future traffic construction. In this paper, Dong Ling Bridge is taken as a living example to illustrate briefly the design principle, design scheme, factors that influence the splice of T beam and the related treatment measure, and the situations of T beam reconstructions.
