Transverse self-balancing antisymmetric cable bent tower cable-stayed bridge structure system
The invention discloses a transverse self-balancing antisymmetric cable bent tower cable-stayed bridge structure system which comprises an upper bridge body structure and a lower supporting structure.The upper bridge body structure comprises cable bent towers obliquely arranged on the two sides of a main beam in an antisymmetric mode, and the upper portions of the cable bent towers comprise staycables, back cables and cable bent tower center columns. The upper end of the cable bent tower center column is connected to the two sides of a transversely-arranged bridge beam body through stay cables and back cables which are arranged on the two sides to form a cable bent tower upper triangular opposite-pull structure, the stay cables are oppositely pulled on the outer side of the bridge beam body, the back cables are anchored to the ends of bridge side beam horizontal supports, and the back cables are anchored to a cable bent tower bearing platform through inclined supports. The problems that an antisymmetric leaning tower needs to be provided with a powerful cable bent tower structure for balancing the transverse stress of the cable bent tower, and a back cable needs to be fixed through a ground anchor are effectively solved. The balance of the transverse stress of the cable bent tower is achieved by balancing the transverse stress of the cable bent tower through the dead weight of an edge beam and the cable force of a self-anchored back cable besides the the dead weight of the leaning tower. A transverse self-balancing structure system is formed.
本发明公开了一种横向自平衡反对称索塔斜拉桥结构体系，包括上部桥体结构和下部支撑结构，所述上部桥体结构包括倾斜反对称布置在主梁两侧的索塔，索塔上部包括斜拉索、背索和索塔中心柱，所述索塔中心柱上端通过两侧设置的斜拉索和背索向横向设置的桥梁梁体两侧连接形成索塔上部三角形对拉结构，所述斜拉索反对称对拉在桥梁梁体外侧，背索锚固在桥梁边梁水平撑端部，背索通过斜撑锚固在索塔承台上。本发明有效解决了反对称斜塔为平衡索塔横向受力需要设置强大的索塔结构，且背索需通过地锚固定等问题，实现了索塔横向受力的平衡除了靠倾斜索塔自重，还通过边梁自重以及自锚背索索力平衡索塔横向受力，形成横向自平衡结构体系。
