Extradosed cable-stayed bridge
The embodiment of the invention provides an extradosed cable-stayed bridge. The extradosed cable-stayed bridge comprises a main beam, at least two bridge piers, at least two bridge towers and a plurality of stay ropes, wherein the main beam is arranged in the extension direction of the extradosed cable-stayed bridge, and the main beam comprises a bridge floor for a train to pass through; the bridge piers and the bridge towers are used for supporting the main beam, and the two bridge piers are respectively arranged on both ends of the main beam in the extension direction; the two bridge towersare arranged between the two bridge piers, each bridge tower comprises a main pier and two tower limbs, the two tower limbs are arranged on both sides of the upper surface of the main pier, a gap forthe main beam to pass through is formed between the two tower limbs, the main beam is arranged in the gap and is fixedly connected with the main pier, the tower limbs are obliquely arranged in the axial direction of the main pier, and the two tower limbs are inclined towards opposite directions; and the stay ropes are located above the bridge floor and are connected with the bridge floor and the tower limbs. According to the extradosed cable-stayed bridge of the embodiment, the passing space of the bridge floor is increased.
本申请实施例中提供了一种矮塔斜拉桥，包括主梁、至少两个桥墩、至少两个桥塔和多个拉索，主梁沿矮塔斜拉桥的延伸方向设置，主梁包括用于供列车通过的桥面；桥墩及桥塔用于支撑主梁，两个桥墩分别设置在主梁延伸方向的两端；两个桥塔设置在两个桥墩之间，桥塔包括主墩和两个塔肢，两个塔肢设置在主墩上表面的两侧，两个塔肢之间形成有用于供主梁通过的间隙，主梁设置在间隙内且与主墩固定连接，塔肢倾斜于主墩的轴向设置，两个塔肢朝向相背离的方向倾斜；拉索位于桥面以上，连接桥面与塔肢。本申请实施例提高了桥面的通过空间。
