Main girder structure for large-span extradosed cable-stayed bridge and construction method thereof
The invention provides a main beam structure for a large-span extradosed cable-stayed bridge, a main beam is arranged in the extension direction of the extradosed cable-stayed bridge, the main beam structure comprises a main bridge pier arranged on a ground foundation, the main bridge pier is used for supporting the main beam, the main beam structure further comprises a support pouring section, a cantilever pouring section and a support system, the support system is arranged on the peripheral side of the main bridge pier and arranged below the support pouring section to support the support pouring section. The cantilever pouring sections extend from the two sides of the support pouring section to the extension direction of the extradosed cable-stayed bridge, the extradoses extend upwards from the centers of the main beams, and stay cables are arranged between the extradoses and each beam section of the cantilever pouring sections. According to the main beam structure for the large-span extradosed cable-stayed bridge, the support system is arranged below the support bridge section, the support system has a supporting effect on the support bridge section, multiple beam sections can be poured at the same time, and the construction period can be shortened.
本发明提供一种用于大跨径矮塔斜拉桥的主梁结构，主梁沿矮塔斜拉桥的延伸方向设置，主梁结构包括设于地面基础上的主桥桥墩，主桥桥墩用于支撑主梁，主梁结构还包括支架浇筑段、悬臂浇筑段以及支架体系，支架体系设于主桥桥墩外周侧，并设于支架浇筑段下方，形成对支架浇筑段的支撑。悬臂浇筑段自支架浇筑段两侧向矮塔斜拉桥的延伸方向延伸，矮塔自主梁中心向上延伸，矮塔与悬臂浇筑段的每梁段之间设有斜拉索。本发明所述的用于大跨径矮塔斜拉桥的主梁结构，通过在支架桥梁段下方设置支架体系，支架体系对支架桥梁段具有支撑作用，能够进行多梁段同时浇筑，可缩短施工工期。
