Continuous rigid frame and suspension cable combined bridge structure system and construction method thereof
The invention provides a continuous rigid frame and suspension cable combined bridge structure system and a corresponding construction method. In the bridge system, a suspension cable main cable is a prefabricated part and comprises a middle span main cable and two side span main cables; a variable cross-section main beam of a continuous structure is fixedly connected to two main piers of a bridge, a bridge tower is fixedly connected to the pier tops of the two main piers to jointly form a tower-beam-pier fixedly connected integral structure, a steel anchor box is arranged on the top of the bridge tower, and the variable cross-section main beam serves as a platform. Steel anchor boxes at the tops of two bridge towers and two beam end anchoring structures are used for erecting prefabricated suspension cable main cables in a three-section mode, a plurality of suspenders which are evenly distributed at equal intervals are hung between the middle of a midspan main cable and a variable cross-section main beam, and the steel anchor boxes, the suspension cable main cables and the suspenders form a suspension cable system. The defects of an existing suspension bridge structure system can be effectively overcome, the advantages of the suspension bridge structure system are integrated, and a more competitive brand new bridge type scheme is provided for the main span of 130-300 m.
本发明提供了一种连续刚构与悬索组合桥梁结构体系及相应的施工方法，该桥梁体系中：悬索主缆为预制件，包括中跨主缆与两边跨主缆；结构连续的变截面主梁固结在桥梁两主墩上，两主墩墩顶上固结桥塔，共同形成塔‑梁‑墩固结的整体结构，所述桥塔顶部设置钢锚箱，以所述变截面主梁为平台，利用两桥塔顶部的钢锚箱与两梁端锚固结构分“三段式”分段架设预制的悬索主缆，所述中跨主缆的中部与变截面主梁之间挂设多根等距均匀排布的吊杆，由钢锚箱、悬索主缆以及吊杆构成悬索系统。本发明可有效避免现有悬索桥桥梁结构体系的不足，综合其优点，为主跨130‑300m跨径提供了一种更有竞争力的全新桥型方案。
