Stayed cable and suspension cable cooperation system bridge
The invention discloses a stayed cable and suspension cable cooperation system bridge, and relates to the technical field of bridge engineering. The bridge comprises at least two bridge towers arranged along the bridge direction, and a main cable and a main beam which are connected with the plurality of bridge towers; the part of the main beam between the two bridge towers comprises two cable-stayed area beam sections, two crossed area beam sections and a suspension cable are; the cable-stayed area beam sections are each arranged close to one bridge tower; the cable-stayed area beam sections are connected with adjacent bridge towers through cable-stayed area stayed cables; the crossed area beam sections are each connected with one cable-stayed area beam section; the crossed area beam sections are connected with the adjacent bridge towers through crossed area stayed cables and are connected with the main cable through crossed area hanging rods; each crossed area stayed cable and each crossed area hanging rod are anchored to different upper chord nodes of the crossed area beam sections respectively; the suspension cable area beam section is located between the two crossed area beam sections; and the suspension cable area beam section is connected with the main cable through a suspension cable area hanging rod. According to the bridge, the anchoring structures of the crossed areastayed cables and the crossed area hanging rods on the main beam are simplified, so that the main beam and the bridge towers are under reasonable stress, and the construction cost is reduced.
本申请公开了一种斜拉悬索协作体系桥，涉及桥梁工程技术领域，其包括沿顺桥向布置的至少两个桥塔、以及连接多个桥塔的主缆和主梁，主梁位于两个桥塔之间的部分包括：斜拉区梁段，其设有两段，分别靠近一个桥塔设置，斜拉区梁段通过斜拉区斜拉索连接邻近的桥塔；交叉区梁段，其设有两段，且分别连接一个斜拉区梁段，交叉区梁段通过交叉区斜拉索与邻近的桥塔连接，并通过交叉区吊杆与主缆连接，每个交叉区斜拉索和每个交叉区吊杆分别锚固于交叉区梁段的不同上弦节点处；悬索区梁段，其位于两个交叉区梁段之间，悬索区梁段通过悬索区吊杆连接主缆。本申请，简化交叉区斜拉索和交叉区吊杆在主梁上的锚固结构，使主梁和桥塔受力合理，并降低工程造价。
