Cable-stayed-suspended cable cooperative system bridge provided with main cable inclined buckle cables and cable-stayed-suspended cable cooperative system bridge method
The invention provides a cable-stayed-suspended cable cooperative system bridge provided with main cable inclined buckle cables and a method, the bridge is provided with main span area inclined buckle cables and side span area inclined buckle cables in a sling-free area, and the main span area inclined buckle cables and the side span area inclined buckle cables are arranged in a V shape; the upper end of the inclined buckle cable is connected with a main cable in a sling-free area through a cable clamp, and the lower end of the inclined buckle cable is anchored on a bridge tower or a stiffening beam near a tower-beam intersection area. In the installation process of the inclined buckle cable system, the inclined buckle cable can obtain the preset tension through a tensioning force control method of the inclined buckle cable or an unstressed length control method of the inclined buckle cable. According to the invention, the vertical rigidity of the main cable of the existing cable-stayed-suspension cable cooperative system bridge can be obviously improved, so that the deflection of the stiffening beam under the live load is reduced.
本发明提出了一种设置主缆斜扣索的斜拉‑悬索协作体系桥梁及方法，该桥梁在无吊索区设置主跨区斜扣索和边跨区斜扣索，主跨区斜扣索和边跨区斜扣索呈V型布置；斜扣索上端通过索夹与无吊索区主缆相连，下端锚固在塔梁相交区域附近的桥塔或加劲梁上。在斜扣索系统的安装过程中，可以通过斜扣索的张拉力控制法，或斜扣索的无应力长度控制法使斜扣索获得预设拉力。本发明可显著提高现有斜拉‑悬索协作体系桥的主缆竖向刚度，从而减小活载下加劲梁的挠度。
