Prefabricated assembled UHPC-corrugated steel web combined box girder bridge and construction method
The invention belongs to the technical field of civil engineering, and relates to a prefabricated assembled UHPC-corrugated steel web combined box girder bridge and a construction method thereof. The bridge comprises a bridge pier and a UHPC-corrugated steel web combined box girder which is arranged on the bridge pier and connected with the bridge pier. The combined box girder is formed by sequentially splicing a plurality of UHPC-corrugated steel web combined box girder sections; each section comprises a UHPC top plate, a UHPC bottom plate, a corrugated steel web and a UHPC transverse partition plate. The UHPC top plate and the UHPC bottom plate are axially arranged in parallel; the corrugated steel web is arranged at the web position; the UHPC transverse partition plate is vertically arranged between the UHPC top plate and the UHPC bottom plate and makes contact with the corrugated steel web; And the UHPC bottom plate is connected with the bridge pier. The structural design is simple, the dead weight of the box girder bridge is remarkably reduced, and the main span of the bridge is greatly increased; the cracking risk is obviously reduced, and the structural durability is improved; the construction is convenient, and the site construction period is greatly shortened.
本发明属于土木工程技术领域，涉及一种预制拼装式UHPC‑波形钢腹板组合箱梁桥及其施工方法；包括桥墩以及置于桥墩上且与桥墩相连接的UHPC‑波形钢腹板组合箱梁；组合箱梁是由多个UHPC‑波形钢腹板组合箱梁节段依次拼装而成；节段包括UHPC顶板、UHPC底板、波形钢腹板和UHPC横隔板；UHPC顶板和UHPC底板轴向平行放置；且波形钢腹板置于腹板位置处；UHPC横隔板垂直置于UHPC顶板和UHPC底板之间且与波形钢腹板相接触；UHPC底板与桥墩相连接。本发明结构设计简单，显著降低箱梁桥自重，大幅提升桥梁主跨跨径；显著降低开裂风险，提高结构耐久性；施工方便，大幅缩短现场施工工期。
