Steel-UHPC combined box girder cable-stayed bridge and construction method thereof
The invention discloses a steel-UHPC combined box girder cable-stayed bridge and a construction method thereof.The steel-UHPC combined box girder cable-stayed bridge comprises a plurality of steel-UHPC combined wide box girder units used for forming a bridge girder, each steel-UHPC combined wide box girder unit comprises a plurality of prefabricated UHPC bridge deck slabs and a steel box girder combined structure, and the prefabricated UHPC bridge deck slabs are connected through UHPC wet joints; and meanwhile, the prefabricated UHPC bridge deck slab and the steel box girder combined structure are connected into a whole through the UHPC wet joints. The steel-UHPC combined box girder cable-stayed bridge has the advantages of being small in shrinkage stress, short in construction period and high in crack resistance. The construction method of the steel-UHPC combined box girder cable-stayed bridge has the advantages that the construction steps can be reduced, and the construction period can be greatly shortened.
本发明公开了一种钢‑UHPC组合箱梁斜拉桥及其施工方法，包括多个用于形成桥梁主梁的钢‑UHPC组合宽箱梁单元，钢‑UHPC组合宽箱梁单元包括多块预制UHPC桥面板和钢箱梁组合结构，各预制UHPC桥面板之间通过UHPC湿接缝连接，同时UHPC湿接缝还将预制UHPC桥面板与钢箱梁组合结构连接成一体。该钢‑UHPC组合箱梁斜拉桥具有收缩应力小、施工周期短、抗裂性能高的优点，该钢‑UHPC组合箱梁斜拉桥的施工方法具有能够减少施工步骤，大幅缩短施工周期的优点。
