Field installation and construction method for large-span composite string truss
The invention discloses an on-site installation and construction method for a large-span composite string truss. The technical problem that a traditional on-site installation and construction method for the large-span truss is not suitable for on-site installation and construction of the fusiform large-span composite string truss is solved. According to the method, finite element simulation calculation analysis is firstly adopted to accurately simulate displacement and internal force of the large-span composite string truss in each stage in the tensioning process; and the configuration of the assembly bracket relative to the cable structure and the large-span composite string truss structure is accurately positioned in the horizontal direction and the vertical direction, so that the construction of the prestressed cable of the large-span composite string truss reaches the design form. The method is scientific and reasonable in design, finite element simulation calculation analysis is adopted, displacement and internal force of the truss in all stages in the tensioning process are accurately simulated, the configuration of the assembly support relative to the cable structure and the truss structure is accurately positioned in the horizontal direction and the vertical direction, and therefore large-span composite string truss prestress inhaul cable construction reaches the design form.
本发明公开了一种大跨度复合张弦桁架现场安装施工方法，解决传统大跨度桁架现场安装施工方法不适用于呈梭形的大跨度复合张弦桁架现场安装施工的技术问题。本发明先采用有限元模拟计算分析以精确模拟大跨度复合张弦桁架在张拉过程中各阶段的位移与内力，再在水平方向和竖直方向精确定位拼装支架相对索结构和大跨度复合张弦桁架结构的位形以使大跨度复合张弦桁架预应力拉索施工达到设计形态。本发明设计科学合理，采用有限元模拟计算分析，精确模拟桁架在张拉过程中各阶段的位移与内力，在水平方向和竖直方向精确定位拼装支架相对索结构和桁架结构的位形，以使大跨度复合张弦桁架预应力拉索施工达到设计形态。
