Large-span deck type cable auxiliary beam arch combined rigid frame bridge and construction method thereof
The invention discloses a large-span deck type cable auxiliary beam arch combined rigid frame bridge which comprises hollow piers, upper chord box girders, lower chord box archs for supporting the upper chord box girders, cable bent towers located over the hollow piers and the upper chord box girders, and stay cables distributed in a beam arch combination section area formed by converging and intersecting the upper chord box girders and the lower chord box arches along the cable bent towers. The upper chord box girders, the lower chord box arches and the hollow piers intersect to form a girder arch triangular area, the upper chord box girders are supported by the hollow piers and the on-arch stand columns in the girder arch triangular area, the hollow piers intersect with arch feet of the lower chord box arches of the side spans and the middle spans, and the on-arch stand columns are evenly distributed on the vertical face and perpendicular to the lower chord box arches. The bearing efficiency of a bridge structure is improved from the aspects of a structural system and a stress mechanism, the common problems of cracking and downwarping of a conventional concrete rigid frame bridge are solved, the spanning capacity of the concrete rigid frame bridge is further expanded, and the large-span deck type cable auxiliary beam arch combined rigid frame bridge has the advantages of being excellent in structural stress performance, high in cost performance, convenient to maintain and the like.
本发明公开一种大跨度上承式索辅梁拱组合刚构桥，包括空心桥墩、上弦箱梁、上支承上弦箱梁的下弦箱拱、位于空心桥墩和上弦箱梁正上方的索塔以及沿索塔分布于上弦箱梁和下弦箱拱汇合相交形成的梁拱结合段区域的斜拉索，所述上弦箱梁、下弦箱拱和空心桥墩相交成梁拱三角区，所述上弦箱梁在梁拱三角区由空心桥墩和拱上立柱支承，所述空心桥墩与边跨和中跨的下弦箱拱的拱脚相交，所述拱上立柱在立面上垂直于下弦箱拱均布；从结构体系、受力机理方面提高桥梁结构的承载效率，克服常规混凝土刚构桥通常出现的开裂及下挠问题，进一步拓展混凝土刚构桥的跨越能力，具有结构受力性能优异、性价比高、养护方便等优点。
