Mid-span tensioned self-anchored cable-stayed bridge and construction method thereof
The invention discloses a mid-span tensioned self-anchored cable-stayed bridge and a construction method thereof, and relates to the field of bridge engineering. Problems that the stability coefficient of a main beam is increased by increasing the height of the main beam or the height of a bridge tower, and construction cost is increased are solved. The bridge comprises bridge tower foundations, bridge towers, the main beam, inhaul cables, a bridge telescopic device and stay cables. The bridge towers are vertically connected to the tops of the bridge tower foundations, the main beam is horizontally supported on the bridge towers, the inhaul cables are connected between the main beam and the bridge towers, the main beam comprises a middle span beam and a side span beam, and one bridge telescopic device is arranged at the 1/4-1/3 span position of each middle span beam; and the stay cables are connected between a bridge tower main beam connecting node and the bridge tower foundations. Theconstruction method comprises the steps that the bridge tower foundations, the bridge towers and the side span beam are poured in sequence, the mid-span beam is installed section by section, the inhaul cables are installed between the main beam and the bridge towers, one bridge telescopic device is installed at the 1/4-1/3 position of the span of each mid-span beam, and the stay cables are installed between the main beam bridge tower connecting node and the bridge tower foundations.
本发明的一种跨中受拉的自锚式斜拉桥及其施工方法，涉及桥梁工程领域。针对现有通过增加主梁梁高或桥塔高度方式提高主梁稳定系数，提高了工程造价的问题。包括：桥塔基础、桥塔、主梁、拉索、桥梁伸缩装置及斜拉索，桥塔竖向连接于桥塔基础顶部，主梁水平支撑于桥塔，拉索连接于主梁和桥塔之间，主梁包括中跨梁和边跨梁，中跨梁1/4～1/3跨径处分别设置一个桥梁伸缩装置，斜拉索连接于桥塔主梁连接节点与桥塔基础之间。施工方法：依次浇筑桥塔基础、桥塔和边跨梁，逐段安装中跨梁，在主梁和桥塔之间安装多根拉索，在每个中跨梁跨径的1/4～1/3处分别安装一个桥梁伸缩装置，在主梁桥塔连接节点与桥塔基础之间安装斜拉索。
