摘要
结合张家口市下广公铁立交桥工程实例,阐述铁路无梁板钢筋混凝土连续刚构桥的技术设计特点及有关问题的处理方式,连续刚构桥具有跨越能力大、与同跨度的连续梁和简支梁比较其梁高最低的优点,该工程的顺利建成通车,为类似桥梁设计提供了一定的借鉴经验。
In the combination with the project example of Xiaguang Highway-Railway Interchange in Zhangjiakou City, the paper states the technical characteristics and the treatment method of relative problems of beamless slab reinforced concrete continuous rigid frame bridge of railway. The continuous rigid frame bridge has greater capacity for spanning. In the comparison with the continuous beam and simple beam with the same span it has an advantage, i.e. its beam height is lowest. This project was smoothly opened to traffic. It provides a certain experience for the similar bridge design for deference.
