整体式桥台斜梁桥的设计与研究

Design and study of integral abutment skew girder bridge

整体式桥台桥梁作为一种新兴的桥梁结构形式,有许多优点,但受力性能十分复杂,给其推广应用带来了许多难题。文章探讨了整体式桥台斜梁桥设计及研究的重点和难点,介绍了桥长、斜交角的限制,以及简化计算思路,为整体式桥台斜梁桥的设计和研究提供一定的理论基础。

The integral abutment skew girder bridge was a rising bridge structure with much virtue,but its loaded performance was very complicated,which brought very difficult spread and use.The focal point and difficult point of integral abutment bridges design and study were discussed in paper,the restrictions of the span and the skew angle were introduced,as well as the simplifying the calculation idea,which provided a theoretical basis for the design and study on the rising bridge structure.
