Non-prestressed corrugated steel web combined box girder bridge structure and construction method
The invention provides a non-prestress corrugated steel web combined box girder bridge structure and a construction method, the non-prestress corrugated steel web combined box girder bridge structure comprises a corrugated steel web combined continuous box girder and a bridge pier, the corrugated steel web combined continuous box girder is erected on the bridge pier, and the corrugated steel web combined box girder comprises a bridge deck, a corrugated steel web and a steel bottom plate; the corrugated steel webs are symmetrically and vertically installed on the two sides of the steel bottom plate, the bridge deck is installed on the upper portions of the corrugated steel webs, and the corrugated steel web combined continuous box girder bridge adopts variable-cross-section girder height in the bridge direction. The combined bridge deck is adopted in the hogging moment area, the perforated steel plates are arranged in the bridge direction, and the transverse steel bars are additionally arranged, so that the bending rigidity and the bearing capacity of the structure are improved, prestressed tendons do not need to be arranged, the construction process is simpler and more convenient, and the construction cost is saved; good application prospects are realized.
本发明提供了一种无预应力波形钢腹板组合箱梁桥结构及施工方法,包括波形钢腹板组合连续箱梁,桥墩,波形钢腹板组合连续箱梁架设于桥墩上,所述波形钢腹板组合箱梁包括桥面板、波形钢腹板、钢底板,波形钢腹板对称竖直安装于钢底板两侧,桥面板安装于波形钢腹板上部,所述波形钢腹板组合连续箱梁桥顺桥向采用变截面梁高。本发明在负弯矩区采用组合桥面板,顺桥向布置开孔钢板并增设横向钢筋,提高结构抗弯钢度和承载能力且无需布置预应力筋,施工工艺更加简便,节省工程造价,其余区段采用混凝土桥面板,使得组合箱梁受力更加合理,具有很好的应用前景。
