Construction method of hybrid beam cable-stayed bridge
The invention relates to the technical field of hybrid beam cable-stayed bridge construction, and provides a hybrid beam cable-stayed bridge construction method which comprises the following steps that a boundary beam main beam framework is moved towards a bridge tower from a bridge abutment until the two ends of the boundary beam main beam framework are connected with the bridge abutment and the bridge tower respectively; a mid-span steel beam is installed on the side, away from the bridge abutment, of the bridge tower, a first side-span concrete part is installed on the side, facing the bridge tower, of the bridge tower, and the first side-span concrete part and the mid-span steel beam are matched in weight and symmetrically constructed; and a mid-span bridge deck slab and a second side-span concrete part are poured, and the mid-span bridge deck slab and the second side-span concrete part are matched in weight and are symmetrically constructed. By means of the construction method of the hybrid beam cable-stayed bridge, the problems that according to an existing construction method of the hybrid beam cable-stayed bridge, due to the fact that the side span is heavy, a full framing method needs to be used firstly for constructing the side span and then constructing the middle span, the construction period is long, and the risk is high can be solved.
本发明涉及混合梁斜拉桥施工技术领域，提供了一种混合梁斜拉桥的施工方法，包含如下步骤：从桥台处将边梁主梁骨架朝桥塔移动直至边梁主梁骨架的两端分别与所述桥台和所述桥塔连接；在所述桥塔背离所述桥台的一侧安装中跨钢梁，在所述桥塔朝向所述桥塔的一侧安装边跨混凝土第一部分，边跨混凝土第一部分与所述中跨钢梁的重量匹配且对称施工；浇筑中跨桥面板和边跨混凝土第二部分，所述中跨桥面板和所述边跨混凝土第二部分的重量匹配且对称施工。使用该混合梁斜拉桥的施工方法，能解决现有混合梁斜拉桥施工方法由于边跨过重，需要先使用满堂支架法施工边跨再施工中跨，施工周期长、风险高的问题。
