Double-span curved beam bridge and bridge construction method
The invention relates to the field of bridges, and discloses a double-span curved beam bridge and a bridge construction method.The double-span curved beam bridge comprises a beam bridge unit, and the beam bridge unit comprises a beam bridge main frame and a web arch assembly erected above the beam bridge main frame; the bridge main frame comprises a first base, curved beams and cross beams, the curved beams and the cross beams are arranged on the two sides of the first base in the second direction, one end of each curved beam is connected with the first base, the other end of each curved beam is connected with the corresponding cross beam, a bridge deck is in lap joint between the two cross beams, and the end, away from the curved beams, of each cross beam is provided with a second base used for supporting the corresponding cross beam in the first direction; the web arch assembly comprises a main web arch and auxiliary web arches arranged on the two sides of the main web arch in the second direction respectively, arch feet at the two ends of the main web arch are hinged to the two curved beams respectively, the arch foot at one end of each auxiliary web arch is hinged to the main web arch, the arch foot at the other end of each auxiliary web arch is hinged to the corresponding curved beam, and buttresses are arranged on the arch tops of the main web arch and the auxiliary web arches. The curved beams and the web arches are combined, and the bearing capacity of the bridge is improved under the condition that the spanning capacity of the bridge is guaranteed.
本发明涉及桥梁领域，公开了一种双跨曲梁桥及桥梁施工方法，其包括梁桥单元，梁桥单元包括梁桥主架以及架设于梁桥主架上方的腹拱组件；梁桥主架包括第一底座、曲梁和横梁，第一底座沿第二方向的两侧均设有曲梁和横梁，曲梁的一端与第一底座连接，另一端与横梁连接，两个横梁之间搭接有桥面板，每个横梁远离曲梁的一端沿第一方向均设置有用于支撑横梁的第二底座；腹拱组件包括主腹拱和沿第二方向分别设置于主腹拱两侧的次腹拱，主腹拱两端的拱脚分别与两个曲梁铰接，每个次腹拱一端的拱脚与主腹拱铰接，另一端的拱脚与曲梁铰接，主腹拱和次腹拱的拱顶上均设置有支墩。本发明组合曲梁与腹拱，在保证桥梁跨越能力的情况下，提高桥梁的承载能力。
