Self-anchored cable-stayed tied arch bridge
The invention discloses a self-anchored cable-stayed tied-arch bridge. The bridge is a beam, arch and cable novel combined system bridge with a main span adopting through rigid arch rib rigid tie barsand a Nielson system flexible inhaul cable, the main span and a side span are three continuous spans, and cable-stayed self-anchored single-rib arches, double-rib arches or multi-rib arches and stiffening beams are arranged between side span continuous beams and arch ribs. And the double-rib arches and the multi-rib arches are transversely and rigidly connected through the cross beams and the wind braces to form a single-width, double-width or multi-width bridge. The bridge adopts a novel construction method of synchronous section-by-section suspension pouring or suspension splicing of beamsand arches. The novel bridge is large in spanning capacity, large in bearing capacity, novel in construction method, low in construction cost, self-balanced in beam arch, safe, free of risks, attractive in appearance, high in applicability and wide in application range. The tied-arch bridge can regain new vitality, the spanning capacity of the combined system bridge is further improved, and the combined system bridge is worthy of application and popularization in bridge engineering of expressways, railways, cities, countries and the like in China.
本发明公开了一种自锚式斜拉系杆拱桥，它是一种主跨采用下承式的、刚性拱肋刚性系杆的、尼尔森体系柔性拉索的、主跨与边跨为3跨连续的、边跨连续梁与拱肋之间斜拉自锚的单肋拱、双肋拱或多肋拱与加劲梁组合的梁、拱、索新型组合体系桥梁，且双肋拱之间、多肋拱之间通过横梁和风撑进行横向刚性连接为单幅、双幅或多幅桥梁。该桥采用梁拱同步逐段悬浇或悬拼的施工新方法。该新型桥梁跨越能力大，承载能力大，施工方法新，建设成本低，梁拱自平衡，安全无风险，梁拱索组合桥型外观美，适用性较强，应用范围广。它将使系杆拱桥重新焕发新的生命力，并进一步提升组合体系桥梁的跨越能力，值得在我国公路、铁路、城市及乡村等桥梁工程中推广应用。
