Beam-arch combination and steel-concrete mixed continuous rigid frame bridge
The invention discloses a beam arch combination and steel-concrete mixed continuous rigid frame bridge and relates to the field of civil engineering bridges. The bridge comprises a steel box girder, wherein upper chord box beams are arranged on two sides of the steel box beam, a lower chord box arch is fixedly arranged at the bottom of the upper chord box beam, the upper chord box-shaped beam andthe lower chord box-shaped arch jointly form a beam-arch combined continuous rigid frame, a middle part of the upper chord box beam is provided with a pier top chord box beam root part, the upper chord box-shaped beam extends towards two sides along a root part of the pier top chord box-shaped beam, a beam arch convergence area beam section is fixedly arranged at an end, away from the steel box beam, of the upper chord box beam, the steel box beam and the lower chord box arches on the two sides jointly form a main span, the steel box beam is arranged in the middle of the main span, and a steel-concrete connecting area is fixedly arranged on the transition section between the steel box beam and the upper chord box beam. The bridge is advantaged in that by arranging the upper chord box-shaped beams and the lower chord box-shaped arches, the spanning capacity of the prestressed concrete continuous rigid frame bridge is improved on the premise that traditional materials and a traditional cantilever construction process are kept.
本发明公开了一种梁拱组合及钢混混合连续刚构桥，具体涉及土木工程桥梁领域，包括钢箱梁，所述钢箱梁两侧均设有上弦箱形梁，所述上弦箱形梁底部固定设有下弦箱形拱，所述上弦箱形梁和下弦箱形拱共同组成梁拱组合连续刚构，所述上弦箱形梁中部开设有墩顶上弦箱形梁根部，所述上弦箱形梁沿墩顶上弦箱形梁根部向两侧伸出，所述上弦箱形梁远离钢箱梁一端固定设有梁拱汇合区梁段，所述钢箱梁连同两侧的下弦箱形拱共同组成主跨，所述钢箱梁设置于主跨中部，所述钢箱梁与上弦箱形梁之间过渡段固定设置有钢混连接区。本发明通过设有上弦箱形梁和下弦箱形拱，在保持传统的材料、传统的悬臂施工工艺的前提下，提高了预应力混凝土连续刚构桥的跨越能力。
