Rigid frame bridge structure and construction method thereof
The invention provides a rigid frame bridge structure and a construction method thereof, and the rigid frame bridge structure comprises a plurality of pile foundations and further comprises a first bearing platform; the second bearing platform is connected with the first bearing platform through a first transverse straining beam; the third bearing platform is separated from the first bearing platform, and the separation line is perpendicular to the extension direction of the rigid frame bridge; the fourth bearing platform is separated from the second bearing platform, the separation line is perpendicular to the extension direction of the rigid frame bridge, and the fourth bearing platform is connected with the third bearing platform through a second transverse straining beam; the multiple pier columns and the multiple main beam blocks are supported on the first bearing platform, the second bearing platform, the third bearing platform and the fourth bearing platform, and therefore the technical problems that in the related technology, due to the fact that the bearing platforms are deeply excavated, and the wall thickness and the reinforcement ratio of the pier columns are increased to improve the anti-seismic performance of the rigid frame bridge, construction is difficult and unsafe, and cost is increased are solved.
本发明提供了一种刚构桥结构及其施工方法，包括：多根桩基，还包括：第一承台；第二承台，其中第二承台通过第一横向系梁与第一承台连接；第三承台，与第一承台分离并且分离线垂直于刚构桥的延伸方向；第四承台，与第二承台分离并且分离线垂直于刚构桥的延伸方向，其中第四承台通过第二横向系梁与第三承台连接；多根墩柱和多个主梁块，支撑在第一承台、第二承台、第三承台和第四承台上，从而解决了相关技术中通过深挖承台、增加墩柱的壁厚和配筋率来改善刚构桥抗震性能所导致的施工困难、不安全以及成本增加的技术难题。
