Corrugated steel-ultrahigh-strength powder concrete combined box girder continuous rigid frame bridge
The invention relates to a corrugated steel-ultrahigh-strength powder concrete combined box girder continuous rigid frame bridge which comprises a pier girder consolidation section and a web girder section, the web girder section is divided into a first web girder section and a second web girder section, and the first web girder section, the second web girder section and the pier girder consolidation section are sequentially connected in the bridge direction. A transverse partition plate is arranged between the first web girder section and the second web girder section, the web girder section comprises a top plate, a double-limb corrugated steel web and a concrete bottom plate which are sequentially arranged from top to bottom, the bottom of the double-limb corrugated steel web of the second web girder section is filled with filling concrete, the top plate comprises a corrugated steel plate arranged on the double-limb corrugated steel web, and a concrete layer formed by pouring ultrahigh-strength powder concrete is arranged on the corrugated steel plate. Compared with the prior art, the rigid frame bridge has the advantages of being high in buckling-restrained capacity, large in span and the like.
本发明涉及一种波形钢‑超高强粉末混凝土组合箱梁连续刚构桥，包括墩梁固结段和腹板梁段，腹板梁段分为第一腹板梁段和第二腹板梁段，第一腹板梁段、第二腹板梁段和墩梁固结段沿顺桥向依次连接，第一腹板梁段和第二腹板梁段之间设有横隔板，腹板梁段包括由上至下依次设置的顶板、双肢波形钢腹板和混凝土底板，第二腹板梁段的双肢波形钢腹板底部填充有灌填混凝土，顶板包括置于双肢波形钢腹板上的波形钢板，波形钢板上设有由超高强粉末混凝土浇筑而成的混凝土层。与现有技术相比，本发明具有抗屈曲能力强和跨径大等优点。
