外海构施工扣挂式支架系统研究

Research on Cable-stayed Suspending and Connecting Support System for V-shaped Pier in Open Ocean

以长周期大涌浪海域的钢混组合刚构桥施工为依托,对用于外海V构施工的扣挂式支架系统进行研究,充分利用承台顶的有限空间,形成扣挂式拉索支撑体系。同时,通过V构体内临时预应力系统优化支架结构,保证施工过程中支架具有足够的刚度,从而提高V构施工质量、缩短工期。

Based on the construction of steel-concrete composite rigid frame bridge in long cycle swell ocean, this paper researches the fastening support system for V-shaped pier in open ocean thoroughly, making full use of the limited space at the top of the cap, forming a fastening support system. At the same time, the support structure is optimized by the V-shaped pier temporary prestressing system, ensuring sufficient rigidity of the support in construction,which can improve the construction quality of V-shaped pier and shorten the construction period.
