Cable-stayed suspension cable cooperative system bridge
The invention discloses a cable-stayed and suspension cable cooperative system bridge, which belongs to the technical field of bridge engineering, and comprises a main beam and at least two bridge towers arranged along the extension direction of the main beam, and the main beam is erected on the two bridge towers; the main beam comprises a suspension cable area beam section and two cable-stayed area beam sections, the two cable-stayed area beam sections are arranged on the two sides of the suspension cable area beam section respectively, and the two bridge towers are arranged at the junctions of the suspension cable area beam section and the two cable-stayed area beam sections respectively. Besides, a suspension cable is arranged between the two bridge towers, a plurality of suspenders are arranged between the suspension cable and the suspension cable area beam section, and the suspenders and the main beam are arranged in a dip angle mode. According to the cable-stayed suspension cable cooperative system bridge, longitudinal displacement of the main beam under the action of live loads, temperature loads, wind loads and braking force can be effectively reduced, meanwhile, the midspan suspension cables and the main beam lock the temperature zero point of the main beam through rigid suspension rods, system temperature self-adaption is achieved, temperature deformation of the main beam is released, and the telescopic length of the main beam towards the two sides is reduced.
本发明公开了一种斜拉悬索协作体系桥，属于桥梁工程技术领域，包括有主梁，沿主梁延伸方向设置的至少两个桥塔，该主梁架设在两桥塔上；该主梁包括一个悬索区梁段和两个斜拉区梁段，两斜拉区梁段分别设置在悬索区梁段的两侧，并且两个桥塔分别设置在悬索区梁段与两斜拉区梁段的交界处。并且，两桥塔之间设置有悬索，该悬索与悬索区梁段之间设置有多根吊杆，且多根吊杆与主梁均呈倾角布置。本申请中的斜拉悬索协作体系桥可有效减小在活载、温度荷载、风荷载和制动力作用下主梁的纵向位移，同时跨中悬索与主梁采用刚性吊杆锁定主梁温度零点，实现体系温度自适应，释放主梁温度变形，降低主梁向两侧的伸缩长度。
