Special-shaped arch bridge with ultra-wide open type light combined bridge floor and construction method of special-shaped arch bridge
The invention discloses a special-shaped arch bridge with an ultra-wide open type light combined bridge floor and a construction method of the special-shaped arch bridge. The special-shaped arch bridge with the ultra-wide open type light combined bridge floor comprises a supporting structure, a combined bridge floor and an arch rib structure, wherein the arch rib structure comprises a middle arch rib located in the middle of the combined bridge floor and two side arch ribs which are arranged on the two sides of the middle arch rib respectively and obliquely arranged outwards, arch feet at the two ends of the middle arch rib and the two ends of the side arch ribs are fixedly connected with the combined bridge floor, the rise span ratio of the middle arch rib is 1/2.5-1/3.5, and the rise span ratio of the side arch ribs is 1/4.0-1/6.0; and the middle arch rib is connected with the combined bridge floor through a plurality of vertical suspenders, the outer side of the side arch rib is connected with the outer side of the combined bridge floor through a plurality of first inclined suspenders which are arranged in an inclined mode, and the inner side of the side arch rib is connected with the combined bridge floor below the side arch rib through a plurality of second inclined suspenders which are arranged in an inclined mode. The special-shaped arch bridge has the characteristics of light and attractive structure, large span, wider bridge width, reasonable stress and convenience and rapidness in construction.
本发明公开了一种超宽桥面敞开式轻型组合桥面异型拱桥及其建造方法，所述超宽桥面敞开式轻型组合桥面异型拱桥包括支撑结构、组合桥面以及拱肋结构，拱肋结构包括位于组合桥面中部的中拱肋以及两根分设于中拱肋两侧并朝外倾斜设置的边拱肋，中拱肋和边拱肋两端的拱脚均与组合桥面固接，且中拱肋的矢跨比为1/2.5～1/3.5，边拱肋的矢跨比为1/4.0～1/6.0；中拱肋与组合桥面之间通过若干根竖直吊杆连接，所述边拱肋的外侧与所述组合桥面的外侧之间通过若干根斜向设置的第一斜吊杆连接，所述边拱肋的内侧与其下方的组合桥面通过若干根斜向设置的第二斜吊杆连接。本发明具有结构轻巧美观、跨度大、桥宽较宽、受力合理、施工便捷快速的特点。
